Answer:
9x² - 24x + 16
Step-by-step explanation:
Formula for the area of the square base = s²
Where,
s = side length = 3x - 4
Therefore:
Area of the base = (3x - 4)²
Expand
(3x - 4)(3x - 4)
3x(3x - 4) -4(3x - 4)
Apply the distributive property
9x² - 12x - 12x + 16
Add like terms
9x² - 24x + 16
Area of the base in standard form = 9x² - 24x + 16
Answer:
9x^2 -24x +16 units^2
Step-by-step explanation:
(3x-4)^2 = 9x^2 -24x +16
3 boys shared a box of chocolate. The first boy got 3/8 of the total and the 2nd boy got 2/5 of the remainder and the 3rd boy got 9. How many chocolates were in the box and how many did the boy with the smallest share get?
Answer:
1. there were 24 chocolates in the box at first.
2. the boy with the smallest share received 6 chocolates.
Explanation:
let's represent the number of chocolates in the box with 8x.
the first boy got ⅜ × 8x = 3x chocolates. now, there are 8x - 3x = 5x chocolates remaining.
the second boy got ⅖ × 5x = 2x chocolates. now, there are 5x - 2x = 3x chocolates remaining.
3x = 9 chocolates
x = 3 chocolates
since the original number of chocolates was represented by 8x, we now know that there were 8 × 3 = 24 chocolates in the box at first.
the first boy got 9 chocolates, the second boy got 6 chocolates and the last boy got 9 chocolates. thus, the boy with the smallest share got 6 chocolates.

An artist pays an art show director $ 86 to reserve a booth at the show and $ 15 per painting sold at the show
The question is incomplete:
An artist pays an art show director $ 86 to reserve a booth at the show and $ 15 per painting sold at the show. Which statement is true?
a. The expression 15 p + 86 represents the total amount of money the artist pays the art show director for selling p paintings at the art show.
b. The expression 15 p + 86 represents the total number of paintings, p , the artist sells at the art show.
c. The expression 86 p + 15 represents the total amount of money the artist pays the art show director for selling p paintings at the art show.
d. The expression 86p+15 represents the total number of paintings, p, the artist sells at the art show.
Answer:
a. The expression 15 p + 86 represents the total amount of money the artist pays the art show director for selling p paintings at the art show.
Step-by-step explanation:
With the information provided, you can say that the total amount the artist pays for selling a certain number of paintings is equal to the result of multiplying the price per painting for the number of paintings plus the amount to reserve a booth at the show. So, the expression that represents this situation 15p+86. According to this, the answer is the expression 15 p + 86 represents the total amount of money the artist pays the art show director for selling p paintings at the art show.

Write an equation of the line passing through the point (5,8) that is parallel to the line 7x + 5y = 3.
Answer:
y-8=-7/5(x-5)
Step-by-step explanation:
find the slope by rewriting the line's equation.
5y=3-7x
5y=-7x+3
y=-7/5x +3/5
since its parallel, the slope will be the same (-7/5)
use the formula y-y1=m(x-x1) for the point (5,8)
y-8=-7/5(x-5)
rearrange in the form y=mx+b if you wish.

This question has two parts. First, answer Part A. Then, answer Part B. Part A Pete is making 8 identical fruit baskets as gifts. Each basket contains some apples and 12 oranges. Pete uses a total of 168 pieces of fruit to make the baskets. Which equation can be used to determine the number of apples, a, that are in each basket? Multiple choice question.
Answer:
a = 21 - 8
Step-by-step explanation:
to determine the number of apples in each basket, first determine the total number of fruits in each basket and subtract it from the number of oranges in each basket
number of fruits in each basket = 168 / 8 = 21
a = 21 - 8

Math problem A homeowner has two rectangular structures in her backyard. The dimensions of the hot tub are 6 feet by 8 feet. The dimensions of the fire pit are 7 feet by 9 feet. The length of the square backyard is 20 feet. What area of the yard is not covered by the hot tub and fire pit?
Answer:
289feet²
Step-by-step explanation:
Area of a rectangle = length x breadth
area of a square = length²
area of the yard that is not covered by the hot tub and fire pit =
Area of the yard - (area of the hot tub + area of the fire pit)
Area of the yard = 20 feet² = 400 feet²
area of the hot tub = 6 feet² x 8 feet² = 48 feet²
area of the fire pit = 7 feet² x 9 feet² = 63 feet²
400 - (48 + 63) = 289 feet²

x hours is represented by the equation below.
y = 45

ОВ.
The number of boxes that can be packed by Ryan and Daniel each decreases over time. Daniel's function has a greater rate of
change than Ryan's function, indicating that Daniel can pack fewer boxes per hour.

Answer:
A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of
change than Ryan's function indicating that Daniel can pack more boxes per hour.
Step-by-step explanation:
Given
Ryan: 3 boxes per hour
Daniel: [tex]y = 4h[/tex]
Required
True statement about their functions
First, we calculate Ryan's function.
In 1 hour, he can pack 3 boxes.
In hours, he can pack 3h boxes.
So, the equation is:
[tex]y = 3h[/tex]
So, we have:
[tex]y = 3h[/tex] ---- Ryan
[tex]y = 4h[/tex] --- Daniel
Both functions represent direct proportional functions.
So, when h increases y also increases.
However, Daniel's function has a greater rate of change because[tex]y = 4h[/tex] implies that he can pack 4 boxes per hour while Ryan can pack 3.
