Answer:

-7/24

Step-by-step explanation:

Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other.

Subtract 2/3 from both sides:

3/8 (-2/3) = r + 2/3 (-2/3)

3/8 - 2/3 = r

Simplify. First, find common denominators. Note that what you do to the denominator you do to the numerator.

(3/8) x (3/3) = (9/24)

(2/3) x (8/8) = (16/24)

Subtract:

(9/24) - (16/24) = -7/24

r = -7/24

Factor as the product of two binomials x^2-3x-10

cestrela7 [59]

Answer:

(x-5)(x+2)

Step-by-step explanation:

Hello there!

Your expression there has a highest power of $x^{2}$ , so there will be two constants that you need to find.

Your last term is -10, so the constants will have a product of -10. Also your middle term is -3x, so the terms will add up to -3

-5 and 2 fit the mold.

Have a great day!

Rewrite the following polynomial in standard form

blagie [28]

Answer:

-7x³ - ⅑x - 1

Step-by-step explanation:

A polynomial written in standard form would be written in such a way that the term with the highest degree comes first, followed by the second highest and so on, then what comes last is the constant.

Given the polynomial -7x³ - 1 - ⅑x, -7x³ with the highest degree comes first, followed by -⅑x, and then the constant, -1, comes last.

Thus, we would have:

✅-7x³ - ⅑x - 1

Write the expression as a square of a monomial.

frozen [14]

Answer:

The square of a monomial is $(9x^2)^2$

Step-by-step explanation:

Consider the provided monomial.

$81x^4$

We need to Write the expression as a square of a monomial.

The above expression can be written as:

$9\times 9\times x^2\times x^2$

$9^2(x^2)^2$

$(9x^2)^2$

Hence, the square of a monomial is $(9x^2)^2$
