<h3>
Answer: 320 square meters</h3>
===================================================
Explanation:
The scale factor 4 means the dimensions of the second rectangle are 4 times larger.
The width of 4 meters bumps up to 4*4 = 16 meters.
The length of 5 meters becomes 4*5 = 20 meters.
So a 4 by 5 rectangle is similar to a 16 by 20 rectangle.
The area of the second rectangle is therefore 16*20 = 320 square meters.
---------------
As an alternative, you can compute the area of the 4 by 5 rectangle to get 4*5 = 20. Then multiply this with 4^2 = 16 to get 16*20 = 320.
The 4^2 = 16 multiplier is the result of squaring the scale factor.
So if you know the dimensions have been multiplied by 4, then the area has been multiplied by 16.
Answer:
Step-by-step explanation:
First question
1 solution
- 6p-12= - 5p Take 6p from both sides
- -12 = -5p - 6p Combine
- -12 = - 11p Divide by - 11
- -12/-11 = p
- 1.09 = p
Second Question
- Infinitely many solutions.
- 5p + 10 = 5p + 10
- No matter what value you use for p, the right side of the equation always equals the left side.
Third question
- y = 25 - 2x
- x = 6
- y = 25 - 2*6
- y = 25 - 12
- y = 13
There are 13 more stops to make.

To answer that think of this as how many groups of 7/8 cups of salad are needed.
If Marion is with four friends, she need salad for five total people.
She will need five groups of 7/8 cups of salad.
This is represented as 5 x 7/8.
5 x 7/8 = 4 3/8 cups of salad
Answer:
Step-by-step explanation:
It is mandatory (required) to use " ^ " for exponentiation:
(3x – 5)^2 = 4
Taking the square root of both sides, we get
3x - 5 = ±2, or
3x = 5 ±2, or
(a) 3x = 7 => x = 7/3, and
(b) 3x = 3, or x = 1
