1/2 and 2/4 I believe those are right
So get b alone.
A=bh
Divide by h
A/h=b
b is alone
And just to rearrange:
b=A/h
Answer:
72
Step-by-step explanation:
68 69 71 71 71 73 74 75 75 78 and then cross off each number until you reach the middle. You will see 71 and 73 next to each other, what's in-between those two numbers? 72!
13x+25=0
13x+25-25=0-25 Since two opposites added give zero, remove them from the expression 13x=-25
36x² - 100 = 4(9x²-25) = 4(3x+5)(3x-5)
B. 4(3x+5)(3x-5)
