Answer:
x = 3
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles
∠ QRT is an external angle, thus
∠ QRT = ∠ RTS + ∠ RST, substitute values
45x = 25x + 57 + x
45x = 26x + 57 ( subtract 26x from both sides )
19x = 57 ( divide both sides by 19 )
x = 3

Answer:
1. 0.35 miles per minute
2. 5.25 miles
Step-by-step explanation:
1. speed is 21 miles per hour
speed per minute = 21/60 = 0.35 miles per minute
2. distance covered in 15 minutes = 15*0.35
= 5.25miles
Answer:
30
Step-by-step explanation:
The midpoint of BC will be a distance from line k that is the average of the distances of B and C: (17+13)/2 = 15. Call that midpoint P. We know distance MP is half of distance MA. This same relationship will hold with respect to the distances from P and A to any line through M. That is, the distance from line k (through M) is twice the distance from P to line k: 30 units.
Answer:
Step-by-step explanation:
We have that the polynomial, has a root of multiplicity 2 at x = 3 and a root of multiplicity 1 at x = -2.
This means the factored form of the polynomial will be.
Also, it was given that, the y-intercept is y=-12.6.
This implies that:
Divide both sides by 18;
Therefore the polynomial is
