Answer:
a = -2
Step-by-step explanation:
5 + 14a = 9a - 5
Subtract 9a from both sides of the equation
5 + 5a = -5
Subtract 5a from both sides of the equation
5 = -5 - 5a
Add 5 to both sides of the equation
10 = -5a
Divide both sides of the equation by -5
a = -2

Answer:
Convert fraction (ratio) 7 / 10 Answer: 70%
2b: If x is 2.1, then one side of the rectangle is 2.1, and another is 2.1*5=10.5. Thus, the perimeter is 2*(2.1+10.5)=2*12.6=25.2.
3: One side of the square with side-length three will not be on the outside, so we have 3*3=9 inches perimeter from the square of side-length 3. The square of side-length 6 has 3 from the top side missing from the outer perimeter, because it coincides with a side of the square of side-length three. This square contributes 6*4-3=33 inches. The total perimeter is 33+9=42 inches.
-110x+40
You need to use the distributive property for this problem
You multiply 22x times -5 (which is -110x) and -8 times -5 (which is 40) to get -110x+40
