Answer:
Your first instinct might be to go ahead and add the x terms together, BUT this would be a bad thing to do! You cannot combine the x2 and 2x, because the first term has an exponent (2) and the second one does not have an exponent; therefore, you cannot add them together!
Step-by-step explanation:
296/21 is the answer hope this helps
1) 4a/5
a% of 80 = a% (80) = (a/100)(80) = 80a/100 = 4a/5
2) 17b/100 or 0.17b
17% of b = (17/100)(b) = 17b/100 [ = 0.17b ]
3) ab/100
a% of b = (a/100)(b) = ab/100

Answer:
C.) -5 and 5
Step-by-step explanation:
Plug in -5 & 5 separately for x.
Plug in -5 for in the equation. Remember to follow PEMDAS. First solve for power, then multiplication.
2(-5)² = 50
2(25) = 50
50 = 50 (True).
Plug in 5 into the equation for x. Remember to follow PEMDAS. First solve for power, then multiplication.
2(5)² = 50
2(25) = 50
50 = 50 (True).
