Answer is 180- (60+70) = 50°
Answer:
(3x-7) (x-7)
Step-by-step explanation:
Answer:
(x²+5)(x-9)
Step-by-step explanation:
Assuming that you are asking to factor by grouping:
x³ - 9x² + 5x – 45
You can group:
x²(x-9) + 5(x-9)
and then combine the x² and 5:
(x²+5)(x-9)
I can’t seem to look at the bottom two answers and the two ( A and B) are not correct. So you’re left with either C or D
The first two negatives cancel out and you're left with positive 4. Now go inside the square root and do the exponent. -4*-4 = 16. Then do the -4*3*1 = -12. Do 16-12 = 4. now the square root of 4 = 2. at the dominator is 2*3 = 6. right now they problem should look like 4+- 2/ 6. from there you split the problem in two. so you have 4+2/6 & 4-2/6 then you solve both problems.
6/6 2/6
1 1/3
1 & 1/3 are your answers. I hope this helped!
