Answer:
(f+4)(f−5)
Step-by-step explanation:
The middle number is -1 and the last number is -20.
Factoring means we want something like
(f+_)(f+_)
We need two numbers that...
Add together to get -1
Multiply together to get -20
4+-5 = -1
4*-5 = -20
Fill in the blanks in
(f+_)(f+_)
with 4 and -5 to get...
(f+4)(f-5)

Answers: A, C, and F</h3>
All of these equations are in the form Ax+By = C
- An equation like x+y = -1 has A = 1, B = 1, C = -1
- An equation like x+4y = 0 has A = 1, B = 4, C = 0
- An equation like 8x-3y = 20 has A = 8, B = -3, C = 20
The lower bound is the smallest value that would round up to the estimated value. A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound and subtract it from the rounded value for the lower bound.
Answer:
-10
Step-by-step explanation:
-4 - 5 + 4 + (-5)
-9 + 4 - 5
-5 - 5 =
-10
