Answer:
Step-by-step explanation:
The area of a triangle is
and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:
That's the height that we will sub into the area formula:
Answer:
y= -6x - 51
Step-by-step explanation:
5y = -6x - 10
Slope: -6
y = -6/5x - 2
Point: (-10,9)
y-intercept: 9 - (-6)(-10) = 9 -60 = - 51
Answer: x = 1
Step-by-step explanation:
2log(x+1) - log (x+3) = log 1
log(x+1)^2 - log (x+3) = log 1
log [(x+1)^2 / (x+3)] = log 1
(x+1)^2 / (x+3) = 0
(x+1)^2 = 0
x = 1 or x = -1 (rejected, as log0 does not exist)
