Answer:

Step-by-step explanation:

(-v² - 3v -8)(3v² + 6v + 3) = -v²*(3v² + 6v + 3) -3v*(3v² + 6v + 3) -8*(3v² + 6v + 3)

= -3v⁴ - 6v³ - 3v² -9v³ - 18v² - 9v - 24v² - 48v - 24

{bring the like terms together}

= -3v⁴ - 6v³ - 9v³ -3v² -18v² -24v² - 9v - 48v - 24

= -3v⁴ - 15v³ - 45v² - 57v - 24

HINT:

-v²*(3v² + 6v + 3) = -v²*3v² + (-v²)*6v + (-v²)*3

= -3v²⁺² - 6v²⁺¹ - 3v²

-3v*(3v² + 6v + 3) = -3v*3v² + 6v*(-3v) + 3*(-3v)

= -9v¹⁺² - 18v¹⁺¹ - 9v

= -3v³ - 18v² - 9v

= -3v⁴ - 6v³ - 3v²

Jennifer made 5 L of punch. Her brother made another 750 mL. If they combine the two batches how many 180 mL servings would they

LiRa [457]

If they combined the tow batches they would equal 5750ml and they would have 31 servings of punch with 180 ml per serving. But they would be left with 94ml

Simplify using positive exponents 1. (5^3)^5 2. 7^-2/5^-2 3. -3(5+27)^0 4. 10^-2

Brrunno [24]

Remember, when you distribute exponents, you distribute them to the existing exponent (if there is one) AND the coefficient. Here's the math:

1. $(5^3)^5$

Distribute $(^5)$ to 5 and $(^3)$

$(5^5)^3^(^5^)$

Multiply the terms accordingly

$25^1^5$

2. $\frac{7^-^2}{5^-^2}$

Multiply the numerator and denominator by

$\frac{7^-^2}{5^-^2}=( \frac{7}{5})^-^2$

Use the Negative Exponent Rule to rearrange the expression

$(\frac{5}{7})^2$

Square the numerator and denominator

$\frac{5^2}{7^2}$

Simplify

$\frac{25}{49}$

3. $-3(5+27)^0 = 0$

If something is multiplied to the power of 0, than it is equal to 0

4. $10^-^2$

For this, we will once again use the Negative Exponents Rule (find the reciprocal and change the negative exponent to its opposite)

$\frac{1}{10^2}$

Simplify

$\frac{1}{100}$

Answers:

1. $25^1^5$

2. $\frac{25}{49}$

3. $0$

4. $\frac{1}{100}$

Hope this helps!

A wire 27 ft long is cut into two pieces. Each piece is bent into the shape of a square. The perimeter of the larger square is t

Alexus [3.1K]

Answer:

Perimeter of the smaller square = 9 ft

Perimeter of the larger square = 18 ft

Step-by-step explanation:

Let

Perimeter of the smaller square = x

The perimeter of the larger square is twice the perimeter of the smaller square.

Perimeter of the larger square = 2x

Total Length of the piece of wire = 27 ft

Total = smaller + larger

27 = x + 2x

27 = 3x

x = 27/3

x = 9 ft

Perimeter of the smaller square = x

= 9 ft

Perimeter of the larger square = 2x

= 2(9)

= 18 ft
