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
43/100 - 223/100
(43x100)-(23x100)/100x100
-18000/100000
(-18000/2000)/(100000/2000)
= -9/5 or -1 4/5

Answer:
14x+4
Step-by-step explanation:
5x+5x+2x+2x+3+3-1-1
5x+5x+2x+2x=14x
3+3-1-1=4
14x+4
Answer:
y = 5
x = 10
Step-by-step explanation:
Remember your 30 60 90 triangle rules.
The 5√3 would equal x√3, so x would equal 5.
The x for the hypotenuse is 2x, so 2(5) is 10.
The y is the x for a 30 60 90 triangle, so y = 5.
