All you have to do is set up 2 proportions, where one paint you know and the other you do not know and make it equal to the ratio as 2 blue : 5 yellow

For example: 1 blue/x yellow = 2 blue/5 yellow, and then cross multiply and solve for x.

Do this for all unknowns, blue and yellow paint making it equal to the ratio and solve for the unknown.

EXPRESS in power notation

lora16 [44]

Answer:

Solution given:

-1/8= $\frac{-1³}{2³}=(\frac{-1³}{2³}=-1³*2^{-3}=-2^{-3}$

2. -64/27

= $\frac{-4^{3}}{3³}=\frac{-4³}{3³}=(\frac{-4}{3})^{3}$

Express in rational number

1. (-3/2)=-3/2*2/2=-(3*2)*(2/2)=-6/4

2. (1/5)=1/5*5/5=<u>5/25</u>

and

(-4/3)³(2/5)-⁴ ÷ (7/4)

(-4³/3³)(2-⁴/5-⁴)÷7/4

(-64/27)(5⁴/2⁴)÷7/4

(-64/27)(625/16)÷7/4

(-64*625/(27*16))*4/7

-2500/27*4/7

-10000/169

(-100/13)²

What is the product of the two binomials below?

Rufina [12.5K]

Answer:

A. 9A² - 16B²

Step-by-step explanation:

(3A + 4B)(3A - 4B)

Distribute:

3A(3A - 4B)

4B(3A - 4B)

Multiply:

3A(3A - 4B)

3A(3A) + 3A(-4B)

9A² - 12AB

4B(3A - 4B)

4B(3A) + 4B(-4B)

12AB - 16B²

Combine like terms:

9A² - 12AB + 12AB - 16B² <== -12AB + 12AB cancels out

9A² - 16B²

Therefore, our final answer is 9A² - 16B²

Hope this helps!
