Lorico [155]

<h2>Answer:</h2><h3>-2x-2</h3>

 $solution \\ {2x}^{2} - x + ( - x - {2x}^{2} - 2) \\ = {2x}^{2} - x - x - {2x}^{2} - 2 \\ = {2x}^{2} - {2x}^{2} - x - x - 2 \\ = - 2x - 2$ 

Hope it helps

Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood.

Orlov [11]

Answer:

Step-by-step explanation:

Two triangular ends
Area of one = 1/2 b * h
b =1.2
h =0.9
Area = 1/2 * 1.2 * 0.9 = 0.54 sq meters
Area of 2 = 2 * 0.54 1.08

Area bottom

L = 3.5 m
w = 1.2
Area = L * W
Area = 3.5 * 1.2
Area = 4.2

Area Back

L = 3.5
W = 0.9
Area = 3.5 * 0.9
Area = 3.15

Area Slanted piece

L = 3.5
w = 1.5
Area = L * W
Area = 3.5 * 1.5 = 5.25

Total = 5.25 + 3.15 + 4.2 + 1.08 = 13.68

The sum of Jim's weight and Bob's weight is 180 pounds. If you subtract Jim's weight from Bob's weight, you get half of Bob's we

Furkat [3]

Answer:

120 pounds

Step-by-step explanation:

We can use systems of equations to solve this problem. Assuming j is Jim's weight and b is Bob's weight, the equations are:

j + b = 180

b - j = 1/2b

Let's get b - j = 1/2b into standard form (b, then j, then the equal sign, then the constant.)

$b - j = \frac{b}{2}\\\frac{b}{2} - j = 0$

Now we can solve using the process of elimination.

$b + j = 180\\\\\frac{b}{2} - j = 0\\\\b + \frac{b}{2} = 180\\\\b + b \cdot 2 = 180\cdot 2\\3b = 360\\b = 120$

Now we know how much Bob weighs, for fun, let's find Jim's weight by substituting into the equation.

$120 + j = 180\\j = 180-120\\j = 60$

So Bob weighs 120 pounds and Jim weight 60 pounds.

Hope this helped!
