PLEASE HELP ASAP!!! Evaluate 7p + 6(p ÷ q)^2 - 2q (if p = 6 and q = 3). Show your work and explain each step.

Arturiano [62]

Answer:

$60$

Step-by-step explanation:

Evaluate 7p + 6(p ÷ q)^2 - 2q (if p = 6 and q = 3)

$7p + 6(p \div q)^2 - 2q\\\\7(6) + 6(6 \div 3)^2 - 2(3)\\\\7(6) + 6(2)^2 - 2(3)\\\\7(6) + 6(4) - 2(3)\\\\42 + 24 - 6\\\\66-6\\\\60$

Hope this helps!

Simplify (4xy)(2x2y)(3xy)3 24x^2y^3 24x^6y^5 216x^3y^3 216x^6y^5

Genrish500 [490]

Answer:

The final answer is D. 216 x⁶ y⁵

Step-by-step explanation:

Let's simplify the expression, this way:

1. Start with the coefficients:

4 * 2 * 3³

4 * 2 * 27

216

2. Variable x:

We have x * x² * x ³ = x¹⁺²⁺³ = x⁶

x⁶

3. Variable y:

We have y * y * y³ = y¹⁺¹⁺³ = y⁵

y⁵

4. Adding the pieces:

We put coefficients and variables together: 216 x⁶ y⁵

The final answer is D. 216 x⁶ y⁵

If r is directly proportional to the square of s and r = 72 when = 12, find r when s = 8.?

Norma-Jean [14]

Answer:

r2=48

Step-by-step explanation:

r1=72

s1=12

s2=8

$r \alpha s \\ \frac{r1}{s1} = \frac{r2}{s2} \\ \frac{72}{12} = \frac{r2}{8} \\ r2 = 8 \times \frac{72}{12} = 48$
