1.) expand
3x - 15 - 5x = 25 + 6x
2.) simplify
-2x - 15 = 25 + 6x
3.) add 2x to both sides
-15 = 25 + 6x + 2x
4.) simplify
-15 = 25 + 8x
5.) subtract 25 from both sides
-15 - 25 = 8x
6.) simplify -15 - 25 to -40
-40 = 8x
7.) divide both sides by 8
-40/8 = x
8.) x = -5
Answer:
a- 10x^2 - 4x + 12

1 foot = 12 inches
52 * 12 = 624 inches per hour
1 hour = 60 minutes
624/60 = 10.4 inches per minute
Add 5+3 raised to the 2nd which givea u (8)^2
do the 5 squared which gives u 1+25-23
evaluate 8^2=64
subtract the sum u should get 64 over 3, 21 and 1/3 or 21.3333333 repeating
Answer:
100
Step-by-step explanation:
discriminant = b^2 - 4ac
here
b = 6, a= 4, c = -4
6^2 -4 •4•-4 = 36 +64 = 100
