Step-by-step explanation:
solve the ineq first then plot on the number line so,
-2(4x + 5) ≤ 30
-8x - 10 ≤ 30
-8x ≤ 40
x ≥ -5
therefore, option A is correct.

Answer:
$40000
Step-by-step explanation:
PRT/100
20000*8*25/100=40000
Answer: choice A or (-25)(-25)=625
Step-by-step explanation:
its choice A because a negative times a negative equals a positive :)
Given:
square shape
Perimeter 28 feet
Find its area
A square has 4 equal sides, so perimeter is 4a
Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a
One side of the the square is 7 ft.
Area of a square is the measure of one side raised to the power of 2.
A = a²
A = (7 ft)²
A = 49 ft²
