Answer:
You will need 1400 cm² of paper
Step-by-step explanation:
When you wrap a gift, you wrap around the entire object. We need to find the total surface area of the prism. A rectangular prism has two rectangular faces on the end. The area of one of those faces is Height (of the prism) times Width.
Rectangular prisms also have 4 sides which are composed of rectangles. The area of one of those rectangles is length (of the prism) by the width.
Now we just need to sum up all of those areas.
![A = 2(H*W) + 4(L*W)\\A = 2(10*14) + 4(20*14)\\A = 2(140) + 4(280)\\A = 280 + 1120\\A = 1400](https://tex.z-dn.net/?f=A%20%3D%202%28H%2AW%29%20%2B%204%28L%2AW%29%5C%5CA%20%3D%202%2810%2A14%29%20%2B%204%2820%2A14%29%5C%5CA%20%3D%202%28140%29%20%2B%204%28280%29%5C%5CA%20%3D%20280%20%2B%201120%5C%5CA%20%3D%201400)
Answer:
Please post a picture of the given triangle.
Step-by-step explanation:
First, since both of the equations are equal to y you can set the equations equal to each other.
y=-2x +1
y=-2x^2 + 3x +1
-2x + 1= -2x^2 + 3x + 1
Second, add 2x^2 and subtract 3x and 1 from both sides.
-2x + 1 = -2x^2 + 3x + 1
-3x -1 +2x^2 +2x^2 -3x -1
________________
2x^2 - 5x = 0
Third, factor out an x.
x(2x - 5) = 0
Fourth, solve for x by setting each factor equal to 0.
x= 0 2x-5=0
+5 +5
_______
2x = 5
---- ----
2 2
________
x=5/2
So the values of x that satisfy the system of equations is 0 and 5/2.
She has enough money, the total will be $95
you add 10+10+75, to get $95
