Answer:

15.8

Step-by-step explanation:

since you're trying to figure out the perimeter of the rectangle you would use the formula 2L + 2W.

3.7 times 2 is 7.4

and 4.2 times 2 is 8.4

so, add 7.4 and 8.4

= 15.8

Answer:

15.8m

Step-by-step explanation:

Your perimeter is given by the sum of four sides of the rectangle:

Perimeter = 3.7m*2 + 4.2m*2 = 7.4m + 8.4m = 15.8m

Step-by-step explanation:

Step 1: Define

7a + 42 + 8 < -10 + 9a - 64a

Step 2: Solve for a

Combine like terms (a): 7a + 42 + 8 < -10 - 55a
Combine like terms: 7a + 50 < -10 - 55a
[Addition Property of Equality] Add 55a on both sides: 62a + 50 < -10
[Subtraction Property of Equality] Subtract 50 on both sides: 62a < -60
[Division Property of Equality] Divide 62 on both sides: a < -30/31

Here we see any number a less than -30/31 would work as a solution to the inequality.
