we have
Equate the expression to zero to find the roots
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
square roots both sides
the roots are
so
therefore
<u>the answer is the option</u>
3/4(2x + 5) = 5(x + 12)
First get rid of any fractions by multiplying my the denominator
4 x 3/4(2x + 5) = 4 x 5(x + 12)
3(2x + 5) = 20(x + 12)
Then get rid of the parentheses
6x + 15 = 20x +240
Then simplify
6x + 15 - 15 = 20x + 240 - 15
6x = 20x + 225
6x - 20x = 20x - 20x + 225
-14x = 225
Now divide on both sides
-14x/-14 = 225/-14
x = -16
Answer:
Hmmmm i'm not sure. I don't have much social confidence but apparently people like talking to me. I just kind of act nice and caring
Step-by-step explanation:
Answe10/5 - 5/5 = 5/5
Step-by-step explanation:
Angle 1 = 115°.
Because angle 4 = 65°, we know that the angle on the other side on 4 (with no number on it) must equal 180° when added to 65°. This is because they are supplementary angles, meaning that they add up to 180°. So if you do 180°-65°, you should get 115°, which is the measure of that angle.
Since the lines are parallel, that means that angle 1 and the angle outside of 4 must be equal, which means that angle 1 = 115°.
Hope this helps!
