Solve the inequality. 9 + 9(x + 7) >= 36 The solution is

x≥ -4

Step-by-step explanation:

9 + 9(x + 7)≥ 36

Subtract 9 from each side

9 -9+ 9(x + 7) ≥ 36-9

9(x + 7) ≥ 27

Divide each side by 9

9/9(x + 7) ≥ 27/9

x+7≥ 3

Subtract 7 from each side

x+7-7 ≥ 3-7

x≥ -4

x >= -4.

Step-by-step explanation:

9 + 9(x + 7) >= 36

9 + 9x + 63 >= 36

9x >= 36 - 63 - 9

9x >= -36

x >= -4.

c

step-by-step explanation:

because of the levels

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
