rewrite the following expression as the product of two binomials:
(x-2)(4x-3)-(x-2)(3x-8)
ANSWER:
Steps:
(x-2)(4x-3)-(x-2)(3x-8)
Expand: -(x-2)(4x-3): -3x+14x-16
=4x^2-11x+6-3x^2+14x-16
Simplify: 4x^2-11x+6-3x^2+14x-16: x^2+3x-10
=x^2+3x-10
Answer:
x = 6, y = -6
Step-by-step explanation:
solve for x and y
x + 3y = -12
y + 3 = -x + 3
add
(x + 3y) + -x + 3 = -12 + y + 3
3y + 3 = y - 9
2y + 3 = -9
2y = -12
y = - 6
x + 3(-6) = -12
x - 18 = -12
x = 6
Answer:
C) No solution
Step-by-step explanation:
Because we know that y=3x-2, we can substitute the value of y into the first equation to get x:
-6x+2y=-6
-6x+2(3x-2)=-6
-6x+6x-4=-6
-4=-6
However, there is one problem! Since both sides are not equal to each other, there's no solution. Therefore, C is the only correct answer.
Answer:
Step-by-step explanation:
It Is -15n-5
The sum of the measures of the angles of an n-sided polygon is
(n - 2)180
You have a 4-sided polygon, so (4 - 2)180 = 2(180) = 360.
The sum of the measures of the angles of the polygon is 360.
Subtract the three measures you have from 360 to find the measure of the 4th angle.
360 - 115 - 65 - 65 = 115
Answer: D. 115 deg
