Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
-8s + 4 = -7s + 21
<u>Step 2: Solve for </u><em><u>s</u></em>
- [Addition Property of Equality] Add 7s on both sides: -s + 4 = 21
- [Subtraction Property of Equality] Subtract 4 on both sides: -s = 17
- [Division Property of Equality] Divide -1 on both sides: s = -17
Answer:
-17 =s
Step-by-step explanation:
-8s +4 = -7s +21
Add 8s to each side
-8s+8s +4 = -7s+8s +21
4 = s+21
Subtract 21 from each side
4-21 = s+21-21
-17 =s

Answer:
4y^6
Step-by-step explanation:
Take out the constants:
40y^14/10y^8
= 40/10 * y^14 / y^8
= 4 * y^(14-8)
= 4 * y^6
= 4y^6

Answer:
I would say 3:30
Step-by-step explanation:
A = L * H
A = 65
L = 2H - 3
65 = H(2H - 3)
65 = 2H^2 - 3H
-2H^2 + 3H + 65 = 0
(-Hh + 13)(H + 5) = 0
-2H + 13 = 0
-2H = -13
H = -13/-2
H = 6.5 <== height is 6.5 inches
H + 5 = 0
H = -5....this wont work because it is negative
L = 2H - 3
L = 2(6.5) - 3
L = 13 - 3
L = 10 <== length is 10 inches
