Answer:
Step-by-step explanation:
x^2 + 10x + 5 - 30 = 0
x^2 + 10x - 25 = 0
x^2 + 10x = 25
x^2 + 10x + 25 = 25 + 25
(x + 5)^2 = 50 <====
Which is the side length of a cube with a volume of 64 m3?
<em>Volume: 64m</em>³
a^3 = 64
<span>\sqrt[3]{64}</span> [/tex] = 4 m

the answer
Check
4 * 4 * 4 = 64 m³
Answer: f(x) = x³ + x² - 26x + 24
<u>Step-by-step explanation:</u>
x = 4 x = -6 x = 1
x - 4 = 0 x + 6 = 0 x - 1 = 0
(x - 4) (x + 6) (x - 1) = 0
(x² + 2x - 24)(x - 1) = 0
x(x² + 2x - 24) -1(x² + 2x - 24) = 0
x³ + 2x² - 24x -x² - 2x + 24 = 0
x³ + x² - 26x + 24 = 0
I think it would be pr qs I'm not entirely sure though
Answer:
43b. (-1, 2)
43a. (1, -3)
36b. Yes: (0,9)
Step-by-step explanation:
<u>43b</u>. x+y=1
-x+y=3
----------------------
2y=4 > y=2
2+x=1 > x=-1
check:
2(-1)+2=0
0=0
<u>43a</u>. can you figure this one out by yourself and then check it? If you can't I will show my work. The answer is above. :)
<u>36b</u>. y-(0)^2=9
y=9
