Answer:
x = 5
or
x = 3
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -8x its coefficient is -8 .
The last term, "the constant", is +15
Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -8 .
-15 + -1 = -16
-5 + -3 = -8
Answer:
9 because 27 divided by 3 is 9
Answer:
60 degrees each
Step-by-step explanation:
For the triangle, the sum of the interior angles is equal to the exterior
Let x and y be interior
Let z be the third angle
w be the exterior
w = x+y
120 = x+y
If the exterior angle is twice of each of the interior remote angles, then;
2x = 2y
x = y
120 = x+x
2x = 120
x = 60
Since x = y, y = 60 degres
From the triangle, the third angle will be 180 - 120
z = 180-120
z = 60
The measures of the 3 angles are 60 degrees each
Step-by-step explanation:
3x-24=-2
3x=-2+24
3x=22
x=22÷3
x=7.333
