Simplify the expression:<br> 1.9b + 8.2(8.8 + 1.2b)
leva [86]

Answer:

11.74b + 72.16

Step-by-step explanation:

In this question, we're going to simplify the expression.

Solve:

1.9b + 8.2(8.8 + 1.2b)

Use the distributive property.

1.9b + 72.16 + 9.84b

Combine like terms.

11.74b + 72.16

Since we can't simplify any further, 11.74b + 72.16 would be your answer.

Which function is equivalent to the following<br> function?
tino4ka555 [31]

Answer: B

For example, x to the power of 1/2 can be rewritten as the square root of x. Any number to the power of a fraction that has a numerator of one can just be rewritten with a radical, with the number underneath and the denominator of the fraction outside the radical. For the above problem, the 5 (numerator of fraction) can just be written as x to the power of 5, such as inside the radical in choice B. But the 7 must be outside, since x to the power of 1/7 is just X to the root of 7.
