Answer:
x = 2, x = -5/2
Step-by-step explanation:
2x² + x - 10 = 0
(2x + 5)(x - 2) = 0
2x + 5 = 0
2x = -5
x = -5/2
x - 2 = 0
x = 2
Answer:
-24
Step-by-step explanation:
Answer:
y=6
Step-by-step explanation:
all you do is add 4 and 2
Using product and quotient property:
log x + log y can be displayed as log xy
Because we're subtracting 2 log z we can use the power property to rewrite this as log z^2
Now, using quotient property we can display this expression as:
<h3>log xy/z^2</h3>
Answer:
21
Step-by-step explanation:
Given
b - 4a ← substitute a = 6 and b = 45 into the expression
45 - 4(6) = 45 - 24 = 21
