Question is in the picture (surface area)
Marina CMI [18]

Answer:

Your answer is 62 square inches

Step-by-step explanation:

You can cross off 1 & 2, as they are too small.

Lets split this up.

(2*3)+(2*3)+(3*5)+(3*5)+(2*5)+(2*5)

2*3 + 2*3 = 12

3*5 + 3*5 = 30

2*5 + 2*5 = 20

30+20+12 = 62

Which number line models the solution set of -2x + 7 &gt; 17?Pls do 2 answers for good measures (and brainliest)
Sidana [21]

Step-by-step explanation:

We can immediately eliminate answers B and C because we have >, meaning that the circle on the number line has to be open.

-2x+7>17

subtract 7 on both sides

-2x>10

divide by -2. remember that dividing by a negative flips the greater than or less than sign.

x<-5

the answer is D
