Answer:

x= 11, -15

Step-by-step explanation:

(4x + 5) + x^2 +1 0) = 180

x^2 + 4x + 15 = 180

x^2 + 4x + 15 - 180 = 0

x^2 + 4x - 165 = 0

x = 11, -15

Answer:

The building is 187.5 feet tall.

Step-by-step explanation:

A nearby person is 6 feet tall, and casts a shadow that is 8 feet long.

This means that the relation between the real height and the shadow is given by:

\frac{6}{8} = \frac{3}{4}

A tall building casts a shadow that is 250 feet long. How tall is the building?*

The real height is three fourths of the shadow. So

\frac{3}{4}*250 = 187.5

The building is 187.5 feet tall.

What would be the slope of the positions (3,3) and (4,5)
Softa [21]

Answer:

m = 2

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Simply plug our coordinates into the slope formula and solve for <em>m</em>:

m = (5 - 3)/(4 - 3)

m = 2/1

m = 2
