Solve the quadratic equation. (x - 4)2 = 36

This isn't a quadratic equation. I'm assuming that you meant to put (x-4)2x=36
2x^2-8x-36=0

I would use the quadratic formula to solve it.

Best of luck!

Using PEMDAS, we know to multiply the two with the inside of the braket. That would give you (2x-8)=36. Then, you would have to add 8 on both side to cancel out the -8 which would leave you with 2x=44. Then you will divide each side by two to get the answer which is x=22

Two angles of a quadrilateral measure 200° and 50°. The other two angles are in a ratio of 2:9. What are the measures of those t

avanturin [10]

Answer:

20° and 90°

Step-by-step explanation:

Let 2x = measure of 1st angle

then 9x = measure of 2nd angle

The sum of the measures of the angles of a quad is 360

200 + 50 + 2x + 9x = 360

250 + 11x = 360

11x = 110

x = 10

2x = 20°

9x = 90°

Which of the following statements best describes the graph of x + y = 4?

joja [24]

Answer: The correct option is, It is a line joining the points whose x and y coordinates add up to 4.

Step-by-step explanation:

The given equation is, $x+y=4$

when we take x = 1 then

$1+y=4$

$y=3$

when we take x = 2 then

$2+y=4$

$y=2$

From this we conclude that the sum of 'x' and 'y' coordinates is always equal to 4.

Hence, the correct answer is, It is a line joining the points whose x and y coordinates add up to 4.

Margo freezes 8 cups of strawberries if this is 2/3 of the total strawberries that she picked how many cups of strawberries did

Goryan [66]

Answer:

12 cups.

Step-by-step explanation:

Let x be the total cups of strawberries picked by Margo.

We have been given that Margo freezes 8 cups of strawberries and this is 2/3 of the total strawberries that she picked.

We need to find x such that 2/3 of x equals 8. We can represent this information in an equation as:

$\frac{2}{3}x=8$

Let us multiply both sides of our equation by 3.

$3*\frac{2}{3}x=3*8$

$2x=24$

Let us divide both sides of our equation by 2.

$\frac{2x}{2}=\frac{24}{2}$

$x=12$

Therefore, Margo picked 12 cups of strawberries.
