Answer:
Step-by-step explanation:
1) Solve for 2x - y = 9
A. Solve for y.
2x - y = 9
B. Subtract 2x from both sides.
-y = 9 - 2x
C. Multiply both sides by -1.
y = -9 + 2x
D. Regroup terms.
y = 2x - 9
2) Substitute y = 2x- 9 into 4x² + 3y² - 2x + y = 16
A. Start with the original equation.
4x² + 3y² - 2x + y = 16
B. Let y = 2x - 9.
4x² + 3(2x - 9)² - 2x + 2x - 9 = 16
C. Simplify.
16x² - 108x + 234 = 16
3) Solve for x in 16x² - 108x + 234 = 16
A. Solve for x.
16x² - 108x + 234 -= 16
B. Move all terms to one side.
16x² - 108x + 234 - 16 = 0
C. Simplify 16x² - 108x + 234 - 16 to 16 x² - 108x + 218
16 x² - 108x + 218 = 0
D. Use the Quadratic Formula.
,
E. Simplify solutions.
4) Substitute into y = 2x - 9.
1) Start with the original equation.
y = 2x - 9
2) Let x =
3) Simplify
s = lw + 2wh
We can take the 'w' out of the right side of the equation:
s = w(l + 2h)
Divide both sides by (l + 2h)
w =
Good luck!
Answer:
please make me brainliset
False.
If (x+1) is a factor of the polynomial, the polynomial must be divisible by (x+1).
In other words, when you divide the polynomial by (x+1), the remainder should be 0.
In this case, however, the remainder is 24.
