2x²+7x+9x-2=38
2x²+16x-40=0
2(x²+8x-20)=0
2(x+10)(x-2)=0
x=-10 or x=2
if we let x=-10 we get negative lengths for some of the segments which is not allowed so discard it. for x=2,
gh=22, hi=16, and gi=38
Answer:
backflip cartwheel
Step-by-step explanation:
First we need to do 12 ÷ 4 to see how many times that goes in. You get 3. Then you do
Answer:
B. 12/13
Step-by-step explanation:
The answer choices suggest that you intend the problem to be interpreted as ...
(8/13)/(2/3) . . . . . parentheses are required
= (8/13) × (3/2) = (8·3)/(13·2) = (8·3)/(2·13)
= (8/2) × (3/13) . . . . making use of the associative property
= 4 × 3/13 = 12/13
_____
Your calculator can help with these. You do need to get the parentheses right.
