Answer:

The answer is 15.

Step-by-step explanation:

Don't forget about the A and H equaling 5. That is there to throw you off. A and B equals 8. Right? Well that's the length. The the A and E is 3. Right? Well that's the height. what you do is cut the triangular prism in half and you end up with a triangular prism with a height of 5. Then you multiply that with 1.5. You get 1.5 by dividing 3 by 2. You then get 7.5. Now multiply that with 2. Your final answer is 14.

Michael has a fish tank that has a length of 7 inches,a width of 6 inches and a height of 8 inches. What is the total surface ar

White raven [17]

Answer:

292 inches^2

Step-by-step explanation:

So to start off this is a picture of the fish tank.

Next we will find the area of the bottom and top rectangles.

The side lenghts for those two is 7 and 8.

So the area of one is 56 and the area of 2 is 112 inches^2.

Now we will find the area of the left and right rectangles.

The side lenghts are 6 and 8.

So the area of 2 is 96 inches^2.

Now for the front and back rectangles.

The side lenghts for those two are 6 and 7.

So the area of both is 84 inches^2.

So after adding all the areas up the surface area is 292 inches^2.

Descompuneti in factori. x^2+4x-5=?

Lapatulllka [165]

<span>Assume that,
x^2+4x-5 = 0 .......(1)
Then, x^2+4x-5 = 0 x^2+5x-1x-5 =0
x(x+5)-1(x+5) = 0
(x+5) (x-1) = 0
We get x=-5 and x=1
Sub x=-5 in equ (1)
(-5)^2+4(5)-5 = 0
-25+20-5 = 0
-25+25= 0
0 = 0
Sub x=1 in equ (1) (1)^2+4(1)-5 = 0
1+4-5 = 0 5-5 = 0
0 = 0
Therefore x value is -5 and 1</span>

The sum of three consecutive even integers is 126. Let x represent the first integer, x + 2 represent the second integer, and x

LekaFEV [45]

We have that (x) + (x+2) + (x+4) = 126 so 3x + 6 = 126 can be used to find the first integer.

3x + 6 = 126
3x = 120
x = 40

The numbers are 40, 42, 44
