If you factor it then your answer will be -3(-3z-5) if you simplify the answer is 9z+15

Answer:

9z+15

Step-by-step explanation:

-3(-6z-5)-9z

You multiply 3 by the numbers in the *( ) and get

18z+15-9z

Then you add any number with the same variable.

18z with -9z is 9z because different signs means subtract and same signs mean to add.

Then this should be your results.

9z+15

P.S Just in case use GOOGLE or the calculator to double check.

You're Welcome!

Answer:

Length = 225 ft

Width = 150 ft

Step-by-step explanation:

If L is the length and W is the width, then:

900 = 2L + 3W

A = LW

Solve for W in the first equation:

3W = 900 − 2L

W = 300 − ⅔ L

Substitute into the area equation:

A = L (300 − ⅔ L)

A = 300L − ⅔ L²

Use calculus to find dA/dL and set to 0, or use the formula for vertex of a parabola.

Using calculus:

dA/dL = 300 − 4/3 L

0 = 300 − 4/3 L

L = 225

Using vertex formula:

L = -b / (2a)

L = -300 / (-4/3)

L = 225

Find the width:

W = 300 − ⅔ L

W = 150

You got the right answers, but the problem says to assume that the length is greater than the width.

Answer:

The answer to your question is below

Step-by-step explanation:

Process

1.- Get two points of each line to find the equation of each line

Continuous line A (-10, 0) B (0, 9)

Dotted line C (-2, -3) D (0, -10)

Slope continuous line m = $\frac{9 - 0}{0 + 10} = = \frac{9}{10}$

Slope dotted line m = $\frac{-10 + 3}{0 + 2} = \frac{-7}{2}$

2.- Get the equation of each line

Continuous line y + 0 = 9/10 (x + 10)

y = 9/10x + 9

Dotted line y + 3 = -7/2(x + 2)

y + 3 = -7/2x - 7

y = -7/2x -7 - 3

y = -7/2x - 10

3.- Find the inequalities

<u> Continuous line</u> (we need the upper area of the line, we use ≥)

y ≥ 9/10x + 9

The <u>Dotted line</u> (we also need the upper area, we use >)

y > -7/2x - 10

Answer:

no it is not

Step-by-step explanation:

Let's use the Pythagorean theorem for this

a^2+b^2=c^2

60^2+63^2=88^2

3600+3969=7744

7569≠7744

This means that this triangle isn't a right triangle
