Answers

Answer 1

Answer:

x³ + 11x² + 18x

Step-by-step explanation:

(x² + 2x)(x + 9)

Step 1: Distribute x²+2x into x + 9.

x³ + 2x² + 9x² + 18x

Step 2: Combine like terms.

x³ + 11x² + 18x

The area of this rectangle is x³ + 11x² + 18x.

Answer 2

Answer:

Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x

Step-by-step explanation:

The height is (x + 9) and the width is (x^2 + 2x) and the the area of the rectangle is equal to: Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x

The slope of the line is 0. It passes through the point (-3,4). Identify two other points on the line. Justify you answer

Answers

Answer:

Two other points: (2, 4) (6, 4)

Step-by-step explanation:

A line with a slope = 0 is a horizontal line [with a y-intercept of (0, b)], given by the linear equation, y = 4.  This means that the y-coordinate will always equal to 4, regardless of its corresponding x-coordinate. Basically, we could choose any x-coordinate to pair with the y-coordinate of 4.

I chose the ordered pairs, (2, 4) and (6, 4).

Attached is a screenshot of the graphed linear equation, y = 4.        

Drew and Danielle are sightseeing for the day. Between the two of them they take 118 pictures. If Drew takes 14 more than three times as many pictures as Danielle, how many pictures for each friend take?

Answers

Answer:

Drew = 92 pictures, Danielle = 26 pictures

Step-by-step explanation:

Amount of pictures Drew has = x

Amount of pictures Danielle has = y

First make a system of equations:

x + y = 118

x = 3y + 14

Then solve with substitution:

(3y + 14) + y = 118

4y = 104

y = 26

x + 26 = 118

x = 92

In the given figure find out the value of x and y ?​

Given info:

all sides are equal in the given triangle

It is an equilateral triangle all angles are equal and each angle is equal to 60°

Given angles are 3y° and 2x°

→ 3y° = 2x° = 60°

→ 3y° = 60° and 2x° = 60°

→ y° = 60°/3 and x° = 60°/2

→ y° = 20° and x° = 30°

Therefore, x° = 30° and y° = 20°

Answer:-

The values of x = 30° and y = 20°

Key Knowledge:-

→ If all sides are equal in a triangle then it is an equilateral triangle

In an equilateral triangle,

→ all sides are equal.

→ all angles are equal.

→ all angles are equal to 60°

a whole pizza is cut into twelfiths. if dexter eats 1/2 of the pizza and landry eats 1/3 of the pizza then what fraction of the pizza remains

Answers

Answer:

Step-by-step explanation:

Start be rewriting your fractions with a common denominator

Multiply [tex]\frac{1}{2}[/tex] by [tex]\frac{6}{6}[/tex] to get [tex]\frac{6}{12}[/tex]

Multiply [tex]\frac{1}{3}[/tex] by [tex]\frac{4}{4}[/tex] to get [tex]\frac{4}{12}[/tex]

These are the fractions of the pizza eaten in twelfths like the pizza is cut into.

Now subtract from [tex]\frac{12}{12}[/tex] which is the whole pizza to find the pizza remaining

[tex]\frac{12}{12} -\frac{6}{12}-\frac{4}{12} =\frac{12-6-4}{12} =\frac{2}{12} =\frac{1}{6}[/tex]

I think you mean to ask what is the measure of angle A.

You can find the third angle of the bottom triangle by 180 - 43 - 35 = 102

The vertical angle above it is also 102.

Then, to find the measure of angle A, you do 180 - 102 - 18 = 60

So, the measure of angle A is 60 degrees.

Answer:

60°

Step-by-step explanation:

Since Angle E is same for both triangles, as vertical angles, the sum of the other two interior angles should be same.

Then we have:

m∠A + m∠B = mC + m∠Dm∠A + 18 = 43 + 35m∠A + 18 = 78m∠A = 78 - 18m∠A = 60

Hi I’m suppose to write an equation and solve for it. I can’t figure out what I’m doing, it’s a straight angle. Thank you if you figure this out!

Answers

Answer:

Equation: 4x+28= 180

x= 38

Step-by-step explanation:

To solve, you should start by trying to find "x". To do this you can use the expression "4x+28= 180"

TO solve 4x+28= 180, first subtract 28 from both sides:

4x= 152

Then divide by 4;

x= 38

Check your work:

M<1= 38+10 -------> 48

M<2= 114+18 -------> 132

132+48= 180

The choice B) 11.4

Step-by-step explanation:

[tex] {x}^{2} + {(5.5)}^{2} = {(12.7)}^{2} \\ {x}^{2} + 30.25 = 161.29 \\ {x}^{2} = 13104 \\ x = 11.4[/tex]

By using Pythagoras theorem :

[tex] {x}^{2} = (12.7) {}^{2} - (5.5)x {}^{2} [/tex]
