Answer:
A = 105 cm²
Step-by-step explanation:
The area (A) of the trapezoid is calculated as
A = 
[ (b₁ + b₂)h ]
where h is the height and b₁, b₂ the parallel bases
Here h = 5 , b₁ = 24 and b₂ = 18 , then
A = [ (24 + 18)5 ]
= (42 × 5)
= × 210
= 105 cm²
Answer:
x-y=2
I don't get why they are asking you what is 2-5. That seems super basic compared to the other question it is with. Since 5-2=3, then 2-5 or -5+2=-3.
Step-by-step explanation:
We are going to use identity x^2-y^2=(x-y)(x+y)
x^2-y^2=10
(x-y)(x+y)=10
(x-y)(5)=10
Since (2)(5)=10, this implies x-y=2.
Answer:
14
Step-by-step explanation:
280 divided by 20 is 14 when you divide by those 2 numbers you get how much they would cost. also 14x20 is 280
A, because 71-32 is equal to 39
C, because 85-46 is also equal to 39
