The area of any prism is base*height.
The main trick in this problem is determining which face is the base, since this is a triangular prism. We need to calculate the area of the triangle base.
11*8/2=44
Now we just need to multiply by the height.(note height is b this case because the prism is actually printed with the base facing towards you.
44*5=220
Done!
So answer choice B 220.
Answer:
220 is the right answer

Which shows a correct way to find the product?
(−8)(0.09)(−125)
A.
(−8)(0.09)(−125) = (−8)(−125)(0.09)
= (1,000)(0.09)
= 90
B.
(−8)(0.09)(−125) = (−8)(−125)(0.09)
= (−1,000)(0.09)
= −90
C.
(−8)(0.09)(−125) = (−8)(−125)(−8)(0.09)
= (1,000)(−0.72)
= −720
D.
(−8)(0.09)(−125) = (−8)(−125)(−8)(0.09)
= (−1,000)(−0.72)
= 720
Answer:
I Think the answer is D, it should be a positive number
what is the solution of the equation 4x + 12 = 48
Answer:
x =9
Step-by-step explanation:
48-12=36
4x=36
divide by 4
x=9
Answer: A) x=9
48-12=36.
36/4=9
More detailed explanation:
4x+12=48
-12 -12
4x = 36
/4 /4
x = 9
Step-by-step explanation:
subtract 12 from both sides , then divide both sides by 4

Angie's rotation maps triangle XYZ to triangle X'Y'Z'. X(3,6) maps to X'(-3, 6) Y(1, -2) maps to Y'(-1, 2) Z(-1,-5) maps to Z (1,5) Which describes the rotation? 180° rotation O 270° clockwise rotation 90° counterclockwise rotation 90° clockwise rotation
Answer:a
Step-by-step explanation:
A
Triangle XYZ is rotated 180° clockwise to form triangle X'Y'Z'.
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation
If a point A(x, y) is rotated 180° rotation, the new point is at A'(-x, -y).
Triangle XYZ is rotated 180° clockwise to form triangle X'Y'Z'.

{
3х + 2y = 4
5x -y=-15
First answer: -2
Second answer: 5
Answer:
(-2,5)
x= -2
y=5
Step-by-step explanation:
I'm going to solve this through substitution
We need a variable by itself (and we also need it to be positive)
We solve for y in the second equation
5x-y= -15
5x+15=y
We can then plug this in for y into the first equation
3x+2(5x+15)=4
and solve for x
3x+10x+30=4
13x= -26
x= -2
We can then plug this value in for x into any of the two beginning equations and solve for y
5(-2)-y= -15
-10-y= -15
-y= -5
y =5
