I think the answer is (B) ?
Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate
(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify
2(2+sqrt(10)) , 2(2-sqrt(10) =x
Answer:
Yes, No, Yes, No.
Step-by-step explanation:
X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
Answer:
1 A= 3 cm
2 C= 37/99
Step-by-step explanation:
Volume is l * w * h
or s³ for cubes
∛27= 3
3/7= 0.43
3/70= 0.04
37/99= 0.3737373737 etc.
37/100= 0.37
