Answer:
x = i, ~1.41i
Step-by-step explanation:
Assuming "integer coefficients" allows imaginary numbers:
(x^2 + 1)(x^2 + 2)
x^2 = -1 = i
x^2 = -2 = ~1.41i

Question
A square has an area of 81 square inches. How long are its sides?
Someone please I need help ASAP !!
Answer:
Step-by-step explanation:
it is like 9x9=81
but yeah like he said it is a square so all sides are the same
but that is if you want to find the parameter
this question is talking about area
so when a question gives you an area you ask yourself what can be multiplied by what in order to give me the area
or since all sides are the same like he said you could just do simple division and do 81/9 which will =9
and since the question mentions that the area is in square inches it is obvious that the answer would be put in inches
answer: 9 inches
4x + 16 ≤ 74 solve the inequality and show your work
Answer:
x ≤14.5
Step-by-step explanation:
4x+16≤74
Subtract 16 from the 74 and that gives you 58
Then divide each side by 4. 58/4=14.5
Hope this helps! sry if I get it wrong! :(
Answer: x ≤ 29/2
Explanation:
Subtract 16 from both sides
4x + 16 - 16 ≤ 74 -16
Simplify
4x ≤ 58
Divide both sides by 4
4x/4 ≤ 58/4
Simplify
x ≤ 29/2
What is the tenth term of the given geometric sequence: -1, 4, - 16, 64, ... ?
А: 262,144
B: 4,194,304
C: -65,536
D: -1,048,576
Answer:
262144
Step-by-step explanation:
Geometric sequence : -1 , 4 , -16 , 64 .....
Ratio = 2nd term ÷ 1st term = 4 ÷ (-1)= -4
a = first term = -1
r = -4
Each term is obtained by multiplying the previous term by (-4)
nth term = [tex]ar^{n-1}[/tex]
10th term = [tex](-1) * (-4)^{9}= -1 * (-262144) = 262144[/tex]

Determine the range of the function graphed above.
A. [-4, 0]
B. (0,4)
C. [4, )
D. (-0, 4]
9514 1404 393
Answer:
D. (-∞, 4]
Step-by-step explanation:
The range is the vertical extent of the graph. The graph extends off the bottom, so the lower end of the range is -∞. The peak values are y=4, so the upper end of the range is 4.
Expressed in interval notation, the range is ...
(-∞, 4]
_____
Additional comment
The right-side bracket is square because the value 4 is included in the range. The left side bracket is rounded because there's no specific number equal to -∞. We can only say the lowest value of y is greater than -∞.
Answer: (-∞, 4]
Step-by-step explanation: Top of function stops at 4, and is negatively continuous.

p is a whole number. 6p is greater than 40 and less than 45. What is the value of p?
Answer:
p = 7
Step-by-step explanation:
i think there's a proper equation to solve these kinds of problems but you can think about numbers times 6 (1x6 = 6, 2x6 = 12, 3x6 = 18,...)
The value of p will be 7.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
p is a whole number.
And, 6p is greater than 40 and less than 45.
Now,
Since, 6p is greater than 40 and less than 45.
Hence, We can formulate;
⇒ 40 < 6p < 45
Solve for p as;
⇒ 40 < 6p < 45
Divide by 6, we get;
⇒ 40/6 < 6p/6 < 45/6
⇒ 6.67 < p < 7.5
Since, p is a whole number.
Hence, The value of p = 7
Thus, The value of p will be 7.

Find the equation of the line. A line that is perpendicular to the graph of 3x +2y =6 and contains the point (6,-3)
9514 1404 393
Answer:
2x -3y = 21
Step-by-step explanation:
The perpendicular line will have an equation with the x- and y-coefficients swapped and one of them negated. The constant will be the value that makes the equation true at the given point.
3x +2y = 6 . . . . . given equation
2x -3y = c . . . . . . coefficients swapped, one negated
2(6) -3(-3) = c = 21 . . . . . the value of c for the given point
The desired equation is ...
2x -3y = 21

Yep sorry again this math is hard
Answer:
<
Step-by-step explanation:
Firstly, you can focus on the scientific notation and calculate which one is bigger. The left side is [tex]10^3[/tex] whereas the right side is [tex]10^4[/tex]. This shows that even if the number before this was bigger, the larger exponent of these two are the bigger number.
[tex]10^3 = 1000\\10^4 = 10000[/tex]
Meaning the correct sign would be the smaller than sign (<) as the right side is bigger than the left.

Mao counts by fives to 30.alana counts by tens to 40.who will say more numbers? Explain
Answer:
Mao will say more numbers
Step-by-step explanation:
Mao will say more numbers because, to get to 30, you must count by fives 6 times. For example, 5,10,15,20,25,30. There are 6 numbers there. On the contrary, Alana is only going to count 4 times. 10,20,30,40. 6 is greater than 4, therefore Mao will say more numbers. I hope this helps!

The graph of a function is given below.
Give all y-intercepts and x-intercepts shown.
If there is more than one answer, separate them with commas.
Click on "None" if applicable.
Answer:
Y-intercept=(0, 2)
X-intercepts=(-4,0) & (-2,0)
Step-by-step explanation:
X and y- intercepts are determined when they pass through either the x or y axis. If the line passes through the x axis it is the x-intercept and vice versa for y.

Use the sequence of operations to answer the question.
1. add 3 to b
2. subtract the result inom 8
3. triple the answer
Answer:
(8-(3+b))3
Step-by-step explanation:
first of all, we have to variables, 3 and b that we are told to add
that is, 3+b
we are now told to subtract the answer from 8
that is 8 minis the answer
= 8- (3+b)
lastly we triple the answer to give
(8-(3+b)3
or
3(8-(3+b)
Yesterday you borrowed $60 from your brother. Every day that you don't pay it back, you owe $2.00 more. So today, day one, you owe him $62.00, on day two you will owe him $64.00, on day three you will owe him $66.00, etc. If you still haven't paid him back, how much will you owe him on day 25?
Answer:
110 dollars.
Step-by-step explanation:
Since every day you owe him 2 dollars more, and its been 25 days, 25 x 2 is 50.
You originally owed him 60, and 50 dollars in late fees, so 60 + 50 = 110.
You owe him 110 dollars.
