A pencil holder shaped like a triangular prisms height is 12 cm, and the volume of the pencil holder is 216 cm3. What is the area of the base of the pencil holder in square centimeters
Answer:
The area of the base of the pencil holder in square centimeters is 18 square centimeters
Step-by-step explanation:
The volume of a triangular prism is given as base area X height.
To get the base area, we can quickly shuffle the order of the terms to make sure that the base area is the subject of the formula.
Base area = volume of prism / height
Base area = 216/12 = 18 square centimeters
Therefore, the area of the base of the pencil holder in square centimeters is = 18 square centimeters

Identify the graphed linear equation?
Answer:
C
Step-by-step explanation:
The first thing I notice is the slope, which is going down, which means this is for sure a negative slope. So any slopes that just include 5 is now crossed off. And since the formula goes like y=mx+b, I believe the answer would be C, because it actually follows the formula as it should. If I'm wrong, pick D for sure.
Answer:
y=-5x-2

What is the coefficients of x4 in the expansion of (1+x)4(1+2x)3.
By the binomial theorem,
(1 + x)⁴ = 1 + 4x + 6x² + 4x³ + x⁴
(1 + 2x)³ = 1 + 6x + 12x² + 8x³
In the expansion of (1 + x)⁴ (1 + 2x)³, we get an x⁴ when multiplying
• x⁴ and 1 to get x⁴;
• 4x³ and 6x to get 24x⁴;
• 6x² and 12x² to get 72x⁴; and
• 4x and 8x³ to get 32x⁴.
Add these up:
x⁴ + 24x⁴ + 72x⁴ + 32x⁴ = 129x⁴

plzzz help answer tyhese
The slope is m=2 in the first picture. Can be done by rise/run.
The second graph has an undefined slope. Using rise/run would get the run value = 0 and that'd make the slope undefined because the denominator cannot be 0.

Point P is the center of the circle in the figure above. What is the value of x?
Answer:
x = 80°
Step-by-step explanation:
To find x, we need to create an equation.
Recall that the sum of all the 4 interior angles of a quadrilateral = 360°.
Therefore:
m<B + m<A + m<C + m<P = 360°
m<B = 20° (given)
m<C = 20° (given)
m<A = ½*x = x/2 (inscribed angle theorem)
m<P = (360 - x)°
Plug in the values and solve for x
[tex] 20 + \frac{x}{2} + 20 + (360 - x) = 360 [/tex]
[tex] 20 + \frac{x}{2} + 20 + 360 - x = 360 [/tex]
Collect like terms
[tex] 20 + 20 + 360 + \frac{x}{2} - x = 360 [/tex]
[tex] 400 + \frac{x}{2} - x = 360 [/tex]
Subtract 400 from each side
[tex] 400 + \frac{x}{2} - x - 400 = 360 - 400 [/tex]
[tex] \frac{x}{2} - x = -40 [/tex]
[tex] \frac{x - 2x}{2} = -40 [/tex]
[tex] \frac{-x}{2} = -40 [/tex]
Multiply both sides by 2
[tex] \frac{-x}{2} \times 2 = -40 \times 2 [/tex]
[tex] -x = -80 [/tex]
Divide both sides by -1
[tex] \frac{-x}{-1} = \frac{-80}{-1} [/tex]
[tex] x = 80 [/tex]
