Answer:

-24

Step-by-step explanation:

Given expression:

3z (2y - 4)²

z = -2 and y = 3

To solve this problem, simply substitute:

3z (2y - 4)² = 3(-2){2(3) - 4}²

= -6(6-4)²

= -6 (2)²

= -6 x 4

= -24

Answer: x = 27

Step-by-step explanation:

2x+3x+45=180º because all of the angles of a triangle add up to 180

5x=180-45

5x=135

x=135/5

x=27

A telephone pole has a wire to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor po

Bumek [7]

Answer:

The height of the pole is 105ft,

Step-by-step explanation:

Let us call $h$ the height of the pole, then we know that the distance from the bottom of the pole to the anchor point is 49, or it is $h - 49$ .

The wire length $d$ is 14 ft longer than height $h$ , hence

$d= h+14$ .

Thus we get a right triangle with hypotenuse $d= y+14$ , perpendicular $h$ , and base $h-49$ ; therefore, the Pythagorean theorem gives

$(h-49)^2+h^2 = (h+14)^2$

which upon expanding we get:

$h^2-98h+2401 = h^2+28h+196$

further simplification gives

$h^2-126h+2205=0$ ,

which is a quadratic equation with solutions

$h =21ft\\h = 105ft.$

Since the first solution $h =21ft$ will give the triangle base length of $21ft-49ft = -28ft$ which is negative; therefore, we disregard it and pick the solution $h = 105ft$ .

Hence, the height of the pole is 105ft.
