Answer:
If the question is saying that length is 7x, then the answer (width) is x-2
The options are H,H,T or T,T,H
HHT: 1/2 x 1/2 x 1/2 = 1/8
TTH: 1/2 x 1/2 x 1/2 = 1/8
HHT or TTH: 1/8 + 1/8 = 2/8 = 1/4
Answer: 1 out of 4 = 1/4 = 25%
<span>6x^2y + 8x^2 − 30y − 40
= 2x^2(3y + 4) - 10(3y + 4)
= (2x^2 - 10)(3y + 4)
= 2(x^2 - 5)(3y + 4)</span>
Answer: x y
-2 15
-1 9
0 7
1 9
2 15
3 25
Step-by-step explanation:you always do the exponent first, then you multiply that by that two, and then you add 7.
