Answer:
80+40x
Step-by-step explanation:
-5x2(2x2-4x-12)
-10(2x2-4x-12)
-20-20+40x+120
-40+120+40x
80+40x
Answer:
Ok
Step-by-step explanation:
We are given the data ho equal to 704 feet and vo equal to 112 feet per second. We apply then kinematics equation: h = ho + vot - 1/2 gt2. Substituting to the given equation,
h = 704 + 112t - 1/2 * 32*t2when h is equal to zero,0 = 704 + 112t - 1/2 * 32*t2t is equal to 11 seconds
The ordered pair (-1, 6) is the solution to the system of equations.
Step-by-step explanation:
Given equations are;
3x+2y=9 Eqn 1
y=4x+10 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
![3x+2(4x+10)=9\\3x+8x+20=9\\11x=9-20\\11x=-11](https://tex.z-dn.net/?f=3x%2B2%284x%2B10%29%3D9%5C%5C3x%2B8x%2B20%3D9%5C%5C11x%3D9-20%5C%5C11x%3D-11)
Dividing both sides by 11
![\frac{11x}{11}=\frac{-11}{11}\\x=-1](https://tex.z-dn.net/?f=%5Cfrac%7B11x%7D%7B11%7D%3D%5Cfrac%7B-11%7D%7B11%7D%5C%5Cx%3D-1)
Putting x=-1 in Eqn 2
![y=4(-1)+10\\y=-4+10\\y=6](https://tex.z-dn.net/?f=y%3D4%28-1%29%2B10%5C%5Cy%3D-4%2B10%5C%5Cy%3D6)
Solution: (-1, 6)
The ordered pair (-1, 6) is the solution to the system of equations.

Solve using cross multiplication of the last two fractions. I will use
to represent the width of the rectangle. ![60*4=w*5](https://tex.z-dn.net/?f=60%2A4%3Dw%2A5)
Multiply. ![240=5w](https://tex.z-dn.net/?f=240%3D5w)
Divide both sides of the equation by
