(-6i)(-4i) would be 24i
A negative times negative is positive. 6 times 4 is 24.
Answer:
there is no diagram !
Please kindly uplode the diagram again
Step-by-step explanation:
The answer should be 37
2(x+8) = 3(x-7)
distribute
2x+16 = 3x-21
Subtract 2x from both sides
2x+16-2x = 3x-21-2x
16 = x-21
Add 21 to both sides
16+21 = x-21+21
Answer:
x = 9.6
x = - 2.6
Step-by-step explanation:
![x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%C2%B1%5Csqrt%7Bb%5E%7B2%7D-4ac%20%7D%20%7D%7B2a%7D)
Ignore the before the ± it wouldn't let me type it correctly.
x² - 7x - 25 = 0
a = 1
b = - 7
c = - 25
