All squares are rectangles, as squares are a subset. 2 is false because rectangles are a subset. 3 is false because not all parallelograms have right angles. 4 is false (look at first sentence in answer.)

Select the correct answer from the drop-down menu. Simplify the expression. 3y3 – 2y[4y – y(y – 3)] – [2y(y + 1) – 3y(y2 –1)] =

Cloud [144]

Answer:

Given the expression: $3y^3-2y[4y-y(y-3)]-[2y(y+1)-3y(y^2-1)]$

The distributive property says that:

$a\cdot (b+c) = a\cdot b+ a\cdot c$

Applying distributive property on the given expression, we have;

$3y^3-2y[4y-y^2+3y]-[2y^2+2y-3y^3+3y]$

again apply the same property we have

$3y^3-8y^2+2y^3-6y^2-[2y^2+2y-3y^3+3y]$

$3y^3-8y^2+2y^3-6y^2-2y^2-2y+3y^3-3y$

Like terms are those terms which have same variables to the same power.

Combine like terms;

$8y^3-16y^2-5y$

Therefore, the simplified form of the given expression is, $8y^3-16y^2-5y$

What I yesss the quotient of (x^3+3x^2+5x+3)/(x+1)

slamgirl [31]

Answer:

x2−2x+3

Step-by-step explanation:

Divide the highest order term in the dividend by the highest order term in divisor

Multiply the new quotient term by the divisor.

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

Pull the next terms from the original dividend down into the current dividend by the highest order term in divisor

Multiply the new quotient term by the divisor.

The expression needs to be subtracted from the dividend, so change all the signs in

The cost of renting a car is 35/we plus $0.25/mi traveled during that week. An equation to represent the cost would be y= 35+0.2

MaRussiya [10]

ANSWER

260 miles

EXPLANATION

The equation that models the cost is

$y = 35 + 0.25x$

If you have a maximum of $100 to spend for the car rental, then we can equation the cost function to

$100 to determine the maximum number of miles you could travel.

$35 + 0.25x = 100$

$0.25x = 100 - 35$

$0.25x = 65$

$x = \frac{65}{0.25}$

$x = 260mi$

Therefore the maximum number of miles you can travel is 260 miles
