90 = 2(x + 5 + 4x)

90 = 2(5x + 5)

90 = 10x + 10

80 = 10x

x = 8

So the width is 8 and the length is 37
I hope this helps.

What are the solutions to the quadratic equation -2x^2 + 6x + 3 = 0?
mario62 [17]

For this, we will be using the quadratic formula, which is x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}, with a=x^2 coefficient, b=x coefficient, and c = constant. Our equation will look like this: x=\frac{-6+/-\sqrt{6^2-4*(-2)*3}}{2*(-2)}


Firstly, solve the multiplications and the exponents: x=\frac{-6+/-\sqrt{36+24}}{-4}


Next, do the addition: x=\frac{-6+/-\sqrt{60}}{-4}


Next, your equation will be split into two: x=\frac{-6+\sqrt{60}}{-4},\frac{-6-\sqrt{60}}{-4} . Solve them separately, and your answer will be x=-0.436,3.436

Question 2
drek231 [11]

Answer:

y=-3x-5

Step-by-step explanation:

6x+2y=-10

2y = -6x-10 (you need to isolate the y and so i took 6x and subtracted it from both sides)

y = -6/2x-10/2 ( dont feel like explaining)

divide them (-6/2 and -10/2) to get

y=-3x-5

Hope i helped
