Answer:
(x − 5) (x + 4)
Step-by-step explanation:
x² − x − 20
Factor using AC method:
1 × -20 = -20
Factors of -20 that add up to -1: -5 and 4
Divide by 1 and reduce: -5/1 and 4/1
(x − 5) (x + 4)
Answer:
1. positive
2. No
(for number 3, I'm not sure if my answer to it is going to be correct)
Step-by-step explanation:
1. the dots look like they are going up
2. there are no outlying dots that look unusual
8x-4y=-4
4y=5+3x
8x(5+3x) =-4
X= 1/5
4y=5+3 x 1/5
Y=7/5
X=1/5 Y=7/5
D. (-2,-6) (1,3) is the correct answer I believe
Answer:
the area of its base=12 cm²
Step-by-step explanation:
volume=base*height
9.6=b*0.8
base=9.6/0.8=12 cm²
