3 0
2(3x+5)=9x+9-3x+1
(2)(3x)+(2)(5)=9x+9-3x+1
6x+10=9x+9-3x+1
6x+10=(9x-3x)+(9+1)
6x+10=6x+10
6x-6x+10=6x-6x+10
10=10
10-10=10-10
0=0

Someone please help me with the surface area
Igoryamba
Surface are just means that you need to find the area of every face, then add. 

TO find the Area of the rectangle do 16*8 = 128

For the triangle the area formula is b*h*1/2 So do 7*8*1/2= 28   

There are four sides total and two triangles and two rectangles so 28+28+128+128= 312

SO the surface area is 312 in cubed

What best describes the distance between two points with coordinates (2,-3) and (-4,2)
Fed [463]

Answer:

Option c (7.8) is the correct alternative.

Step-by-step explanation:

The given points are:

(x₁, y₁) = (2, -3)

(x₂, y₂) = (-4, 2)

As we know,

The distance between two points will be:

= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

On substituting the values, we get

= \sqrt{(-4-2)^2+(2-(-3))^2}

= \sqrt{(-4-2)^2+(2+3)^2}

= \sqrt{(6)^2+(5)^2}

= \sqrt{36+25}

= \sqrt{61}

= 7.8 \ units

dem82 [27]
Their sum can be both equal, or greater. If you have 3/8 and 6/8, you would get 9/8 or 1 and 1/8. Which is greater than 1. Also if you add 2/6 and 4/6, you get 6/6 or 1. proving that both are possible.

There are 12 students in the pep squad.Three students are wearing white shirts.Six students are wearing blue shirts. What fracti
Viktor [21]

Answer:

\frac{3}{4}

Step-by-step explanation:

Total number of the students in the pep squad = 12 students

The number of the students wearing white shirts = 3 students

The number of the students wearing blue shirts = 6 students

Either white or blue shirts indicate that the students wearing white shirt or blue shirt.

Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students

So,

The fraction is:- \frac{9}{12}=\frac{3}{4}
