As it is emphasized above, the area (A) of a square is the square of its sides (l),
A = l²
The area of the square should be 120 ft². Substituting this to the equation,
120 ft² = l²
Solving will give us an answer of l being approximately equal to 10.95 ft.
Hope i'm right

Answer:
Step-by-step explanation:
Total cost
C (x) = 35+ 60x
Where,
Fixed cost= $35
Variable cost = 60x
x= number of hours of work
Total cost is the addition of fixed and variable cost
C (x) = 35+ 60x
C(5)= 35 + 60(5)
= 35 + 300
=335
C(5) = 335
C(5) = 335 is Olivia's total cost of hiring the electrician
x=5 is the electrician's number of hours of work
35= fixed cost of hiring the electrician
60(5) = 300 is the variable cost of hiring the electrician for 5 hours
It has 1 pair of parallel sides.
Our inequality is 3(x-1) - 4x ≥-3. We can solve this like we solve for x in a regular equation. If I multiply 3(x-1), our new inequality is 3x -3 - 4x ≥ -3. If we add 3 to both sides and subtract 4x from 3x we have -x ≥ 0. But we want the value of x to be positive, not negative. So we multiply both sides by -1 and change the sign from greater than to less than. We get x<span> ≤ </span>0.
Answer:
1. 14
2. 20
3. 12
4. -400
5. 6
6. 21
7. 11
8. 16
9. 40
10. 49
11. 12
12. IDK
Step-by-step explanation:
1. 16-2=14
2. 16+4=20
3. 6 X 2 = 12
4. -400/-10 (negative divided by a negative equals a positive) = 40
5. 6 X 6 = 36
6. 16+5=21
7. 23-12=11
8. 4 X 16 = 64
9. 36-16=20, 20 X 2 = 40
10. 400-8=392, 392/8= 49
11. 912-612=300, 300/25 = 12
12. Sorry too confusing.
