Answer:
a = - 8
Step-by-step explanation:
A polynomial divided by factor (x - h) has a remainder given by f(h)
Here the divisor is (x - 2), thus f(2) gives the remainder, that is
2³ + 2(2)² - 7(2) + a = 4 ← 4 being the remainder
8 + 8 - 14 + a = 4, that is
12 + a = 4 ( subtract 12 from both sides )
a = - 8
Answer:
x = 8
Step-by-step explanation:
The measure of an arc is equal to the angle at the centre subtended by the arc.
The sum of the 3 arcs = 180° , then
5x + 6 + 83 + 51 = 180
5x + 140 = 180 ( subtract 140 from both sides )
5x = 40 ( divide both sides by 5 )
x = 8
Answer:
$124
Step-by-step explanation:
2 tires costs $62
so double that and you have
62*2=124
