Answer:

4a^2-6b^2+12

Step-by-step explanation:

(a^2 - 2b^2 + 3) - (4b^2 - 5) + (3a^2 + 4)

distribute the negative sign to each term in the 2nd expression

a^2-2b^2+3-4b^2+5+3a^2+4

combine like terms

What value of R makes r/ -11 = (-3) true

marissa [1.9K]

Answer:

The value of $r=33$ which makes the equation true.

Step-by-step explanation:

Given the equation

$\frac{r}{-11}=-3$

We have to find the value of r for which the equation must be true.

solving the equation

$\frac{r}{-11}=-3$

Multiply both sides by -11

$\frac{r\left(-11\right)}{-11}=\left(-3\right)\left(-11\right)$

$r=33$

Therefore, the value of $r=33$ which makes the equation true.

VERIFICATION:

Putting $r=33$ in the equation

$\frac{r}{-11}=-3$

$\frac{33}{-11}=-3$

$-3=-3$ ∵ $\frac{33}{-11}=-3$

L.H.S = R.H.S

Therefore, the value of $r=33$ which makes the equation true.
