Answer: x = 3
Step-by-step explanation: 3x3=9 + 1 + 1 = 11 and there are 11 on the other side.
Answer:
![- \frac{2}{13}](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B2%7D%7B13%7D%20)
Step-by-step explanation:
30w-w-6-5w-4=-5w-6-8+3w
30w-w-4=-8+3w
29w-4=-8+3w
29w-3w=-8+4
26w=-8+4
26w=-4(divide bother side by 26)
w=-2/13
To solve the surface area of a triangular prism, first solve the base area, and one of the outer sides. Multiple the outer side by 3, add up the base, then you get the surface area.
You can find out triangle area by multiplying the base length by height.
Answer:
One Factor: x-9
Step-by-step explanation:
The polynomial function, P(x)=x³-8x²-29x+180
To verify: P(9)=0
Put x=9 into polynomial
![P(9)=9^3-8\cdot 9^2-29\cdot 9+180](https://tex.z-dn.net/?f=P%289%29%3D9%5E3-8%5Ccdot%209%5E2-29%5Ccdot%209%2B180)
![P(9)=0](https://tex.z-dn.net/?f=P%289%29%3D0)
At x=9, P(9)=0
Therefore, x-9 must be factor of P(x).
when divide x³-8x²-29x+180 by x-9 get remainder 0
Factor quadratic equation
Three factors are (x+5), (x-4) and (x-9)
Answer:
Area = 3.897
Step-by-step explanation:
Remark
What you are subtly being told is the side of an equalateral triangle = P/n.
n = the number of sides
n = 3
P = 9
side = 9/3 = 3
The area of an equalateral triangle given 1 side is
Area = sqr(3) * s^2 /4
Area = 3.897
