In left one)
the 3 angles are equal so the sides are equal then we can say
then x is 30÷11
the right one) is exactly similar
(8x + 2y) - (7x + 2y) = 30 - 24
X = 6
Every triangle is 180 degrees, so each other angle should have 20
Answer:
The factors are (5x + 3) and (2x + 1)
Step-by-step explanation:
When you need to factor a quadratic, and the coefficient of the x² is not 1, use the slide and divide method.
The general form of a quadratic is ax² + bx + c
Factor: 10x² + 11x + 3
Here a = 10, b = 11, and c = 3
Step 1: Multiply ac, we SLIDE a over to c. Notice the 10 is gone for now..
x² + 11x + 30
Step 2: Factor this (this step will always factor)
x² + 11x + 30 = (x + 5)(x + 6)
So the factors are (x + 5)(x + 6), but we now need to DIVIDE by a, since we multiplied it into c before. We divide the constants in the factors...
(x + 5/10 )(x + 6/10 )
Now reduce the fractions as much as possible...
(x + 1/2 )(x + 3/5)
*If they don't reduce to a whole number, SLIDE the denominator over as a coefficient of x....
(2x + 1)(5x + 3) *2 slide over in front of x, 5 slide over in front of x, the fractions are gone!
These are our factors!
Answer:
y=1
Step-by-step explanation:
the "mx" part of the equation is the slope, since we need the slope to be zero, there won't be anything in the "mx" part. The "+b" bart of the equation is the y-intercept, since we need the y-intercept to be one, the "+b" part will be 1.
