First simpliify
(3r^2+4)(2r-1)=
(3r^2+4)(2r)+(3r^2+4)(-1)=
(6r^3+8r)+(-3r^2-4)=
6r^3+8r-3r^2-4=
put back
6r^3-3r^2+8r-4-8r^3+6r^2=
-2r^3+3r^2+8r-4
I'm assuming this is trig - is this all for one triangle and is it right?
Answer:
Step-by-step explanation:
- 14-ounce ⇒ 42 teaspoons of sugar
- 14/14 ounce ⇒ 42/14 = 3 teaspoons of sugar
- 1-ounce ⇒ 3 teaspoons of sugar
Answer:
4a²+62a+49
Step-by-step explanation:
since (a+b)^2= a^2+2ab+b^2
(3a +7)² – 5a(a-4)
simplify the equation first
9a²+42a+49-5a²+20a
= 4a²+62a+49
Answer:
No Solution
Step-by-step explanation:
perimeter
2√6 - √15 = 4.9-3.9 = 1
-3√3 = -5.19 you can't have a negative length.
and because of that the answer is no solution to both perimeter and area.
if the teacher was just oddly trying to have you show what you know
P = 1+1+ -5.2 - 5.2 = -8.2
A 1x -5.2 = -5.2
