(b2 – 4ac). sorry if this doesnt help it doesnt make sense on my screen it shows a weird equation
Step-by-step explanation:
<span>2d= a-b/b-c solve for a
Okie, you mean: 2d=a-b:(b-c)
If that, we have a= 2d+b:(b-c)
Done!</span>
To factor this you need values that add up to 2 and multiply to -15
So you get 5,-3 then you put it into your equation for you b value
X^2+5x-3x-15
Then you can factor by grouping
X(x+5)-3(x+5)
So your factors are
(X+5)(x-3)
Answer:
16 cm
Step-by-step explanation:
The curve shows displacement in cm. The maximum value of the curve is 16, so the maximum displacement is 16 cm.
Simplifying the expression (x - 2y) + (3x + 4y).
Work:
(x - 2y) + (3x + 4y)
Combine like terms.
x + 3x = 4x
-2y + 4y = 2y
Reform the expression.
4x + 2y
Simplified Expression: 4x + 2y.
