12-17/-5-(-2) so divison first,it will become 12+3.4-(-2) =two minuses will become a "+"
So,12+3.4+2=17,4
ANSWER: 17.4
Answer:
Step-by-step explanation:
MX = XN
5r² + 2r + 52 = 4r² + 12r + 27
5r² - 4r² + 2r - 12r + 52 - 27 = 0
r² - 10r + 25 = 0
(r - 5)² = 0
r - 5 = 0
r = 5
4r² + 12r + 27
4•5² + 12•5 + 27
4•25 + 60 + 27
100 + 60 + 27
187

Answer:
b(4) = -8
Step-by-step explanation:
We are to find the 4th term.
n = 4
b(n) = 1(-2)ⁿ⁻¹
b(4) = 1(-2)⁴⁻¹
b(4) = 1(-2)³
b(4) = 1(-8)
b(4) = -8
The answer is 4^10
How to do it:
4^2•4^8 goes into
4^2+8 which 2+8=10
So,
The answer: 4^10
