Answer:
H = 5 , W = 8 , L = 16
Step-by-step explanation:
Answer:
< W ≅ < P.
Step-by-step explanation:
< W ≅ < P.
< W is the refection of < P over the x-axis.
Since the area of a triangle is in the form
area=0.5(base)(height)
height=base+7
let base=x
area=0.5(x)(7+x)
30=3.5x+0.5x^2
multiply the equation by 2
60=7x+x^2
subtract 60 from both sides
x^2+7x-60=0
(x-5)(x+12)=0
thus x=5 or x=-12 since we are only considering positive answers
x=-12 is rejected
so base=5 and height=5+7=12
The answer is 1.
EXPLANATION
The commutative property of multiplication states that two numbers can be multiplied in either order.
