The value of x in given equation 4(2x + 10) = 0 is -5
<em><u>Solution:</u></em>
Given that we have to find the value of "x" in the given equation
Given equation is:
4(2x + 10) = 0
The value of the variable is found by adding, subtracting, multiplying or dividing both sides of the equation to simplify the equation and isolate the variable.
The goal is to have the variable on one side of the equation and numbers on the other.
Let us first multiply 4 with terms inside bracket
4(2x + 10) = 0
8x + 40 = 0
8x = -40
Thus the value of "x" is -5
Answer:
She should aim 6 feet down the wall
Explanation:
The diagram attached sketches the situtation.
Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.
Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:
x/4 = y/2 ⇒ x = 2y
You have other equation:
x+ y = 18
Substitute
2y + y = 18
3y = 18
y = 18/3
y = 6 ← this is the distance down the wall where the ball should hit
x = 2(6) = 12
Then, she should aim 6 feet down the wall.
