2. Area of the entire figure = 14f + 20 units².
Perimeter of the entire figure = 6f + 18 units².
3. D. 8.
4. 11/15
<h3>How to Find the Perimeter and Area of a Rectangle?</h3>
Perimeter = 2(length + width)
Area = (length)(width).
2. Decompose the shape into two rectangles, rectangle 1 and rectangle 2.
Length of rectangle 1 = f
Width of rectangle 1 = 4
Area of rectangle 1 = (f)(4) = 4f units²
Length of rectangle 2 = 2f + 4
Width of rectangle 2 = 5
Area of rectangle 2 = (2f + 4)(5) = 10f + 20 units²
Area of the entire figure = 4f + 10f + 20
Area of the entire figure = 14f + 20 units².
Perimeter of the entire figure = 2f + 4 + 5 + f + 4 + f + 2f + 5
Add like terms
Perimeter of the entire figure = 6f + 18 units².
3. A factor of 44 is any number that can divide 44 without a remainder. 8 is not a factor of 44 because it cannot divide 44 without a remainder. So, the answer is: D. 8.
4. 33/45 = (3 × 11) / (3 × 15)
= 11/15

Answer:
I'm pretty sure its the 3rd answer
4a + 6b = 10
2a - 4b = 12...multiply by -2
----------------
4a + 6b = 10
-4a + 8b = - 24 (result of multiplying by -2)
------------------add
14b = - 14
b = -14/14
b = -1
2a - 4b = 12
2a - 4(-1) = 12
2a + 4 = 12
2a = 12 - 4
2a = 8
a = 8/2
a = 4
so 12a = 12(4) = 48 <==
I believe it’s correct, but i’m not smart
Answer:
A'B'= 3 cm and B'D' = 1.6 cm
Step-by-step explanation:
First of all, we are told that the scale factor = 1/5
Now,we know that If the scale factor is less than 1, then the dilation is a reduction.
Thus, in this question the dilation is a reduction.
For us to calculate the dimensions of the dilated rectangle, we'll multiply the original dimensions by the scale factor
Thus;
A'B' = AB(1/5)
A'B' = 15(1/5) = 3 cm
B'D' = BD(1/5) = 8(1/5) = 1.6 cm
Thus, The length of each side of the dilated rectangle are;
A'B'= 3 cm and B'D' = 1.6 cm
