1) Let f(x) be x^3+5x^2+2x+1
Since f(x) is divided by x+1,
R= f(-1) = (-1)^3 + 5(-1)^2+2(-1) + 1
= -1+5-2+1
= 3
2) Let f(x) be x^3 - 6x + 5x +2
Since f(x) is divided by x-5,
R= f(5) = x^3 - 6x^2 + 5x +2
= 5^3 - 6(5)^2 + 5(5) +2
= 125 - 150 + 25 + 2
= 2
Answer:
x = 6
Step-by-step explanation:
this figure involves two triangle and one rectangle
for area of rectangle= Length * Width = 16 * 8 = 128 feet^2
for area of one triangle = 1/2 * base * height = 1/2 * x *8 = 4x
for two triangles = 8x ft^2 total
whole area = two triangles + one rectangle
176 = 8x + 128
8x =48
x = 6
If
x+y=-4
y-3x=16 or we cn write as
x+y=-4
-3x+y=16
i multiply the first equation by 3
3x+3y=-12
-3x+ y=16
4y=4
y=1
x+1=-4
x=-5
Answer:
-195 degrees
Step-by-step explanation:
we can subtract 360 from 165 to find the negative coterminal angle.
165-360=-195
