Answer:
A = 160 mm²
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = bh ( b is the base and h the height )
Given P = 52 and P = 2(b + h) , then
2(b + h) = 52 ( divide both sides by 2 )
b + h = 26 ( substitute b = 16 )
16 + h = 26 ( subtract 16 from both sides )
h = 10
Then
A = 16 × 10 = 160 mm²

See below
Step-by-step explanation:
Given that
<h2>C = 5t + 10</h2>
We can simply take t as 1,2, 3 and so on and put it in the above equation. After finding out C, we can plot the points accordingly.

Answer:
x=2
Step-by-step explanation:
So 9x+3=-7+7x+14
Subtract 3: 9x=4+7x
Subtract 7x: 2x=4
x=2
