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).

Given number is 78/14.
We have to find two whole numbers between which given number 78/14 lies.
Let's convert that into mixed fraction.
To do that we divide 78 by 14 to find the quotient.
We see that 14 goes 5 times into 78 and leaves remainder of 8.
So we can rewrite 78/14 as
.
means little more than 5 but less than 6.
So required two whole numbers are 5 and 6.

Answer:
x = (4r +3)/(r +2)
Step-by-step explanation:
Collect x terms, then divide by the coefficient of x.
x(r +2) = 4r +3
x = (4r +3)/(r +2)
