Answer:
4(x+3)²+4
Step-by-step explanation:
4x²+24x+40=0
using the equation above
a:4 b:24 c:40
4(x+(24÷2x4))² + (40-(24²÷4x4))
4(x+3)²+(40-36)

In the diagram below, AB and BC are tangent to O. What is the measure of
AC?
Answer: D. 112°
Step-by-step explanation: Just answered it...
The measure of arc AC, if The line segment AB and BC are the tangents drawn to the circle, and The measure of angle CBA, ∠ CBA = 68°, is 112°, so option D is correct.
What is circle?A circle is a two-dimensional object made up of points that are spaced out from a given point (center) on the plane by a fixed or constant distance (radius).
Given:
The line segment AB and BC are the tangents drawn to the circle,
The measure of angle CBA, ∠ CBA = 68°,
The measure of the major arc, AC = 248°,
Calculate the measure of the minor arc as shown below,
∠ CBA = Major arc - minor arc / 2 (Tangent circle theorem)
68 = 248 - AC / 2
68 × 2 = 248 - AC
136 = 248 - AC
AC = 248 - 136
AC = 112°
Thus, the measure of arc AC is 112°

While attempting to multiply the expression (2-5i)(5+2i) a student made a mistake.
(2-5i)(5+2i)= 10+4i -25i - 10i^2
=10+4(-1)-25(-1) - 10(1)
=10-4+25-10
=21
What is the error?
Answer:
The left side of the equation is ignored
i is treated as -1, which it is not, it is instead the square root of negative 1.
To solve it properly we get:
(2 - 5i)(5 + 2i)
= 10 + 4i - 25i - 10i²
= 10 + 21i + 10
= 20 - 21i
Answer:
The error is that, the student replaced i with -1 which is wrong as i = √-1
And he has replaced i^2 with 1 while i^2 = -1
Step-by-step explanation:
Given two numbers that are being multiplied are:
(2-5i)(5+2i)
We will solve the question to get the right result so that the error can be detected.
So, multiplying both
[tex]= 2(5+2i)-5i(5+2i)\\=10+4i-25i-10i^2\\=10-21i-10(-1)\ \ \ as\ i^2 = -1\\=10-21i+10[/tex]
The error is that, the student replaced i with -1 which is wrong as i = √-1
And he has replaced i^2 with 1 while i^2 = -1
Simplify 3 ( x + 2 ) − 2 ( x 2 + 2x − 4 ).
Which of the polynomials below represents the answer written in standard form?
Select one:
a. - 2x 2 − x + 14
b. - 2 + 7x + 2x 2
c. - 3x 4 + 14
d. 2x 2 + 7x − 2
Answer:
The polynomials that represents the answer is -2x² - x + 14 ⇒ a
Step-by-step explanation:
Let us solve the question
∵ The expression is 3(x + 2) - 2(x² + 2x - 4)
→ Multiply each bracket by the number before it
∵ 3(x + 2) = 3(x) + 3(2)
∴ 3(x - 2) = 3x + 6
∵ 2(x² + 2x - 4) = 2(x²) + 2(2x) + 2(-4)
∴ 2(x² + 2x - 4) = 2x² + 4x + (-8)
→ Remember (+)(-) = (-)
∴ 2(x² + 2x - 4) = 2x² + 4x - 8
∴ 3(x + 2) - 2(x² + 2x - 4) = (3x + 6) - (2x² + 4x - 8)
→ Multiply the (-) by all the terms in the 2nd bracket
∴ 3(x + 2) - 2(x² + 2x - 4) = 3x + 6 - 2x² - 4x + 8
→ Add the like terms
∵ 3(x + 2) - 2(x² + 2x - 4) = -2x² + (3x - 4x) + (6 + 8)
∴ 3(x + 2) - 2(x² + 2x - 4) = -2x² + (-x) + 14
∴ 3(x + 2) - 2(x² + 2x - 4) = -2x² - x + 14
∴ The polynomials that represents the answer is -2x² - x + 14

The integer values of x that satisfy the given inequality are {-2, -1, 0, 1, 2, 3, 4}.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -2<x≤4.
The integer values of x that satisfy the inequality are
{-2, -1, 0, 1, 2, 3, 4}

Step-by-step explanation:

Answer:
-20
Step-by-step explanation
To make the sentence into an equation it would be y+13=(-17). To solve this you would need to get y by itself. To do this, you would make the equation y+13-13 , since you need to do the same thing from both sides, it would be y+13-13=(-17)-13 . Simplify the equation to make y=(-7)-13 . Counting back 13 from -7 gets you to -20 . Finally you get to y=(-20) , so the answer is -20

Answer: BOTTLE 1 =0.0297 BOTTLE 2 =0.0289
Step-by-step explanation:
In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50 km is covered in 5.5 hours, the unit rate will be 50 km/5.5 hours = 9.09 km/hour
bottle 1: $2.97/100 oz = unit rate
bottle 2: $5.78/200 oz=unit rate
BOTTLE 1 =0.0297
BOTTLE 2 =0.0289
Anthony downloaded 8 total items onto his phone. The games he purchased were $2.00 each and songs were $1.00. How many of each did he buy after spending $11.00?
Answer:
he downloaded 9 songs and 1 game
Step-by-step explanation (3x2= 6) (5x1= 5) (3+5= 8) $6.00 + $5.00 = $11.00
so add 3 items to the games that would be $6.00 so 5 items would remain put the rest of those items into the music that would be 5x1 =$5.00. So $6.00+$5.00= $11.00 so the answer is $11.00.

Answer:
The interest is: $2550.00
Step-by-step explanation:
I = P x r x t
P is the principal amount, $12000.00.
r is the interest rate, 4.25% per year, or in decimal form, 4.25/100=0.0425.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 12000 × 0.0425 × 5 to get that:
The interest is: $2550.00

Answer:
∠Z = 34°
∠T = 56°
Step-by-step explanation:
You can solve for x using the measure of the right angle:
90 = 3x +6
30 = x +2 . . . . . divide by 3
28 = x . . . . . . . . subtract 2
Then the measure of T is ...
∠T = 2x° = 2(28)° = 56°
∠Z is its complement: 90° -56° = 34°
The angle measures are ...
m∠Z = 34°
m∠T = 56°
