Answer:

Hi!!

The answer is = 0

Step-by-step explanation:

1. Distribute

3(2+4)=12

6+12=12

2. Subtract 12 from both sides of the equation

6 + 12= 12

6 + 12 − 12 = 12 − 12

3.Simplify

part A. 6 + 12 − 12 = 12 − 12

6x = 12 - 12

part B. 6x = 12 - 12

6x = 0

Hope this helps!! =)

Answer:

I may be wrong, but it should be around 37301.18 Canadian dollars

Step-by-step explanation:

The  Chevy Volt costs  in Canada is 37,888 Canadian Dollar

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit

1 United States Dollar = 1.28 Canadian Dollar

According to the question

Chevy Volt costs in the United States  =  $29,600

As, per  current marked value

1 United States Dollar = 1.28 Canadian Dollar

Cost in Canada =  29,600 *  1.28 Canadian Dollar

                         =   37,888 Canadian Dollar

Hence, the  Chevy Volt costs  in Canada is 37,888 Canadian Dollar

Answer:

a. the sign is interchange

it should be = x^2 - 3x + 4 - x^3 - 7x + 2

Answer:

see explanation

Step-by-step explanation:

(a)

The student has distributed the second parenthesis by 1 instead of - 1

(b)

Given

(x² - 3x + 4) - (x³ + 7x - 2)

distribute the first parenthesis by 1 and the second by - 1, that is

= x² - 3x + 4 - x³ - 7x + 2 ← collect like terms

= - x³ + x² - 10x + 6

Answer:80,65,20

Step-by-step explanation:

In general, a unique triangle may always be drawn if three side lengths are given and the sum of any two is greater than the third. c) More than one triangle can be drawn with Angle A = 40°, Angle B = 60° and Angle C = 80°. The angles sum to 180°, so at least one triangle may be drawn.

Answer:

2,616.67cm³

Step-by-step explanation:

Find the diagram attached

volume of the cone = πr²h/3

r is the radius = 10cm

h is the height = 25cm

Substitute

V = 3.14(10)²*25/3

V = 314*25/3

V = 7850/3

V = 2,616.67cm³

Hence the volume of the cone to the nearest hundredth is 2,616.67cm³

Answer:

105

Step-by-step explanation:

To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.

To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.

−1−126 (−12−24+9)

Combine like terms:

−1−126 (−12−24+9)

−1−126 (−3−24)

Then you'll have to distribute:

−1−126 (−3−24)

−1+378 + 3024
