Answer:

128

Step-by-step explanation:

The two angles form a straight line so they add to 180

2m+62 + 3m +143 = 180

Combine like terms

5m+205=180

Subtract 205 from each side

5m+205-205=180-205

5m = -25

Divide by 5

5m/5 = -25/5

m = -5

We want to find the angle so we substitute the value of m into the the formula for the angle.

< RBM =3m +143 = 3(-5) +143 = -15+143 =128

Find a polynomial with a degree of 3, and the zeros 1,7, & -4 with no other zeros.

jarptica [38.1K]

Answer:

$f(x)=(x+4)(x-7)(x-1)$

Step-by-step explanation:

zeroes are when you plug in that x value and get y=0

therefore if you set x = that number and solve for 0 you get a "function"

multiplying these together will yield the complete 3rd degree polynomial

x = 1

x-1=0

x=7

x-7=0

x=-4

x+4=0

$f(x)=(x+4)(x-7)(x-1)$

If needed you could expand but I'm too lazy
