~kites have adjacent sides equal~
x = 3x-12
move 3x to the other side as a negative number
-2x = -12
divide both sides by -2
-12 divided by -2 is 6
so, x is equal to 6
but, we aren't done yet because the questions asks for the value of angle b
substitute the value we found into the equation for angle b
3(6)-12
36-12
24
so, angle b has a value of 24 degrees
7x + 7 = 112
7x = 105
x = 15
4y + 112 = 180
4y = 68
y = 17
answer is A.
x = 15, y = 17
Answer:
Step-by-step explanation:
Horse A travels twice the distance horse B travels.
It is because the distance, the circumference of circle, is the function of the radius. The circumference is directly proportional with the radius.
Since r₁ = 2r₂, the distance is:
- C₁ = 2πr₁ = 4πr₂
- C₂ = 2πr₂
The time of travel is same so the difference is reflected in the speed.
The horse A has twice the speed of horse B.

Answer:
see below
Step-by-step explanation:
zeroes = -6 and -8
y = (x+8)(x+6) expand to
y = x^2 + 14x + 48
