Answer:
problem 1: h=a/b problem 2: 5
Step-by-step explanation:
First problem: a=bh
First you have to flip the equation so bh=a
Next you have to divide both sides by b.
bh/b=a/b
so h=a/b
Second problem: 45ft is the area and 9ft is the base so to find the height you have to divide the area by the base
If you only have the base and height you would multiply them to find the area. If you only have area and height you divide area by height to get base.
You have to divide 45 by 9, the answer would be 5.
Hope this helped!
Exponental law

so
√(81y^5)=√81 times √(y^5)
√81=9 or -9
√(y^5)=y^2 times√y
answer is 9y^2 times √y or -9y^2 times √y
Answer:
A≈99.33
Step-by-step explanation:
=lw+l(w
2)2+h2+w(l
2)2+h2=5·5+5·(5
2)2+72+5·(5
2)2+72≈99.33034
2x+3+51 = 100
2x+54=100
2x= 46
X=23
maybe try quizzlet that would really help i swear
