Answer:

The value of the expression when a=−2, b=3, and c=−8 is 38.

Step-by-step explanation:

Consider the provided expression.

$-ab^3-ac$

We need to solve the expression when a=−2, b=3, and c=−8.

Substitute the respective values in the provided expression.

$-(-2)(3)^3-(-2)(-8)$

Simplify the expression.

$(2)(27)-(2)(8)$

$54-16$

$38$

Hence, the value of the expression when a=−2, b=3, and c=−8 is 38.

Pani-rosa [81]

Answer:

Yes, this is a valid inference because she took a random sample of the neighborhood.

As we can see, Sue's survey was perfectly random and without any prejudice.

18% of the families, according to her research, would volunteer at the shelter. According to her, 18% of the local households should be required to volunteer at the animal shelter.

Therefore, given that she chose a representative sample of the area, her conclusion is valid.

A recipe calls for 3/4 cup of butter. Angie wants to triple the recipe, but she has only 1 5/8.

Lyrx [107]

Let's start out by tripling the original recipe to see how much butter Angie needs.

$\frac{3}{4} * 3 = total$
$\frac{3* 3}{4} = total$
$\frac{9}{4} = total$
$2 \frac{1}{4} = total$

So we need $2 \frac{1}{4}$ cups of butter, but Angie only has $1 \frac{5}{8}$ . Let's subtract what Angie has from the total to see how much more she needs.

$2 \frac{1}{4} - 1\frac{5}{8} = n$
$\frac{9}{4} - \frac{13}{8} = n$
we will need the least common denominator for both fractions
$\frac{2}{2} *(\frac{9}{4}) - \frac{13}{8} = n$
$\frac{18}{8} - \frac{13}{8} = n$
$\frac{5}{8} = n$

So Angie need $\frac{5}{8}$ cups more of butter for the recipe.

Q=p(r+s) solve for p

Reil [10]

Q = p(r + s)
Use the distributive property
Q = pr + ps
Q = p x r + p x s
Q = p x p + r x s
Q = p^2 + rs
Subtract rs from both sides
Q - rs = p^2
Square root both sides
sqrt Q - rs = p
