Answer:
2x + 6
Step-by-step explanation:
Each term in the parenthesis is multiplied by the 2 outside, that is
2(x + 3)
= (2 × x) + (2 × 3)
= 2x + 6
Answer:
112.2ft
Step-by-step explanation:
As can be seen in the attached diagram, The top of the building is at C.
The distance from the man to the building is |BD| and the height of the man is |AB| where his eye level is at B.
We are required to find the height |CE| of the building.
Now |AB|=|DE|, (opposite sides of a rectangle).
Tan 65° = |CD|/59
|CD|=59 XTan65°=107.23
The height of the building |CE|=|CD|+|DE|=107.23+5=112.23ft
The height=112.2ft ( to the nearest tenth)

A square root has to be two of the same number
Answer:
m = 5
Step-by-step explanation:
Let's convert 5x - y = 20 to slope-intercept format: y = mx + b
5x - y = 20
-y = -5x + 20
y = 5x - 20
Now, we can input the y-value(5) to find the x-value(m)
5 = 5m - 20
25 = 5m
m = 5

2x + 3y = 1200
3y = -2x + 1200
y = -2/3x + 400......slope = -2/3....y int = (0,400)...x int = (600,0)
start at (0,400)...and since ur slope is -2/3, go down 2 spaces, and to the right 3 spaces...plot this point...then go down 2, and to the right 3...plot this point....keep doing this and u should cross the x axis at (600,0).
