Answer:
The answer is 130 feet
Step-by-step explanation:
Using Pythagoras' Theorem:
120² + 50² = diagonal²
diagonal² = 16900ft
diagonal = √16900
= 130ft

Answer:
1
Step-by-step explanation:
1) First, place the given equation in slope-intercept form (
format) to find its slope easier. Isolate the y:

So, the equation of the line in slope-intercept form is
. When an equation is in slope-intercept form, the
, or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.
2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.
To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as
-- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
Distribute then add
a(b-c)=ab-ac
-2.5(1 -2n) - 1.5n
-2.5(1-2n)= -2.5-(-5n)=-2.5+5n
now add the other bit
-2.5+5n-1.5n
-2.5+3.5n
B is a corect answer
find others
distribute and add last 2 choices
D=-2.5-3.5n
E=-2.5+3.5n
E is correc
t
answers to pick are B and E
