You need to subtract 7 from both sides, is how I'm interpreting it. So 0>-11
The answer is 1.
Use the slope formula to solve.
m=
Substitute the corresponding values into the equation.
m=
m=
m=1
The answer is: width = t - 9
A = l * w
A = t² - 4t - 45
l = t + 5
t² - 4t - 45 = (t + 5)w
Step-by-step explanation:
Given the Arithmetic sequence

An arithmetic sequence has a constant difference d and is defined by







as


∵ 





∵ 

∵ 
Therefore, the indicated nth partial sum of the arithmetic sequence is 1530.
ANOTHER METHOD
as

n = 30

and

so


Answer:
x ≈ 36.1
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan61° =
=
( multiply both sides by 20 )
20 × tan61° = x , then
x ≈ 36.1 ( to the nearest tenth )
