Answer:
10: (2m+12)(2m+12)
11: (2r-12)(2r-12)
Step-by-step explanation:
4m^2+48m+144
all positive so factored also all positive
(2m+12)(2m+12)
4r^2-48r+144
middle value is negative but others are positive. this means two are negative
(2r-12)(2r-12)
Answer:
a
Step-by-step explanation:
it's a right triangle so we can use the pythagorean theorem to find h
pythagorean theorem: a^2+b^2=c^2
h^2+19^2=21^2
h^2+361=441
h^2=80
h≈ 8.9ft
Answer:
12.25%.
explanation :
I add 8.25% and 4 since you are trying to find the interest of his account earn after 4 years. 8.25 + 4= 12.25. Yea so that is how I get my answer.
Answer:
r = 40/π exact answer
r = 12.7 decimal approximation
Step-by-step explanation:
arc length formula
s = (∅/360) * 2πr
s = (∅/180) * πr
--------------------------------
Plug in the givens
10 = (45/180) * πr
10 = .25πr
Divide both sides by .25
40 = πr
divide both sides by π
40/π = r
r = 40/π exact answer
r = 40/3.14
r = 12.7 decimal approximation
