Ralph wants to build a rectangular deck with a predefined area of 792 feet squared. One side of the deck will be 54 feet longer than the other. To find the side lengths, he first writes the equation (x)(x+54)=792 and later simplifies it to (x-12)(x+66)=0, where x is the length of the shorter side. Which of these are the side lengths, in feet, of the rectangular deck? Select all that apply. A. 42 B. 54 C. 12 D. 66 E. 120
Answer:
C.12 and D.66
Step-by-step explanation:
(12+54)(12)=792
66*12=792

Answer: Q1: D. Distribute 3 through the parenthesis
Step-by-step explanation:
As for the second question, I am not sure how to begin. Sorry
Answer:
For the first question: 3(p - 3) = 2p + 7, the first step would be to distribute 3 to both terms in the parentheses
For the second question:
6n + 11 = -7 + 3n
-3n -3n
3n + 11 = -7
-11 -11
3n = -18
3n/3 = -18/3
n = -6
Check:
6(-6) + 11 = -7 + 3(-6)
-36 + 11 = -7 + -18
-25 = -25, since these match n definitely equals -6

Which is the correct classification of the value 7pi?
A-Real, Rational, integer
B-Real, Rational
C-Irrational, Integer
D-Real, Irrational
Please Help Me ; ^;
Answer: Real, irrational
Step-by-step explanation:
Real because it is an actual measurement. Irrational because π can't be expressed as a fraction. Not an integer because integers are whole numbers.
The correct classification is -Real, Irrational
What is irrational number?Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.
Irrational numbers are real numbers that cannot be represented as a simple fraction. These cannot be expressed in the form of ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.
Given number: 7* pi
Here, 7 is the real number.
But pi is real but not rational number.
pi is an irrational number.
Hence, the correct classification of 7 pi is Real, Irrational.

If the measure of Angle F G H is 64 degrees and the measure of Angle E G D is (4 x + 8) degrees, what is the value of x? Lines E H and D F intersect at point G. 14 18 64 116
Answer:
x = 14
Step-by-step explanation:
Angle FGH and EGD are vertical angles, so they will have the same measurement.
so basically 64 = 4x + 8
subtract the 8 = 56
divide 56 by 4
x = 14

Please help asap ty just for numbers 29 31 and 32
Answer:
105, D, 13,9899/138530? not sure on that one
Answer:
29.) D
31.) 145 girls
32.) 13,986 , 13,967
Step-by-step explanation:
For 29 you need to find the total cost of each item. 2x1 would be $2 for the water, 1x3 would be $3 for the sandwich. Remember what operation you used to find the products. In this case, it would be D.
For 31 you need to find the number of girls at the tournament. For that you would write out the total cost of children, and subtract the number of boys from that to get the total.
For 32 you just need 2 random numbers that will round up to 14,000. Any number that is 5 or above will round up, and any number that is 4 and under will round down.

The figure below is made of two identical triangular prisms. What is the volume of the figure?
Answer:
A triangular prism is 1/2 the volume of a rectangular prism with the same dimensions.
V = BH (Base x Width) of a triangular its 1/2BH
The base is 10 x 5, 50 is the base.
The height is 6, and that would be 300 / 2 since it's triangular so its 150 inches squared for one. Since there are 2.
The total volume is 300 inches squared.

All you're doing is [tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex] or [tex]\frac{5}{8}[/tex] ×[tex]16[/tex]
-
[tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex]
so 5 × 16 = 80
and
8 × 1 = 8
The fraction becomes
[tex]\frac{80}{8}[/tex]
