9x8 is 72 because you just ad 9 eight times like 9+9+9+9+9+9+9+9 or you could do 8 nine time like 8+8+8+8+8+8+8+8+8

Harman [31]

Answer:

+2n^5 - 9n^2 + 5n

Step-by-step explanation:

To solve the expression

-n(-2n^4+9n-5)

first we will multiply -n with each term and then find their products.

When doing multiplication the powers will be added and co-efficient will be multiplied.

-n(-2n^4+9n-5)​\\-n(-2n^4) -n(+9n) -n(-5)\\+2n^5 - 9n^2 + 5n

Hi how can I graph this if it dosn't have a slope?<br> 1. y = (2/3)x - 1 <br> y = -x + 4
12345 [234]

System of Linear Equations entered :

[1] y - 2x/3 = -1

[2] y + x = 4

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[1] 3y - 2x = -3

[2] y + x = 4

Graphic Representation of the Equations :

-2x + 3y = -3 x + y = 4

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -y + 4

// Plug this in for variable x in equation [1]

[1] 3y - 2•(-y +4) = -3

[1] 5y = 5

// Solve equation [1] for the variable y

[1] 5y = 5

[1] y = 1

// By now we know this much :

y = 1

x = -y+4

// Use the y value to solve for x

x = -(1)+4 = 3

I hope this help you

Find the volume of a triangle prism with the following dimensions triangle base: 5ft
Andrews [41]
Hey there :)

We know the volume formula of a triangular prism
Volume = base area × height of prism

We are given:
Base of triangle = 5 ft
Height of triangle = 3 ft
Height of prism = 7.5 ft

Apply the formula
V = \frac{1}{2} ( 5 )( 3 ) × 7.5
   = 7.5 × 7.5
   = 56.24 ft³
