Radda [10]

Answer:

V(x) = 4x^3  - 24x^2+35x

Step-by-step explanation:

Given

V(x) = (7 - 2x)(5 - 2x)(x)

Required

Expand the expression

V(x) = (7 - 2x)(5 - 2x)x

Expand bracket

V(x) = (7 - 2x)(5 * x - 2x * x)

V(x) = (7 - 2x)(5x - 2x^2)

Further expand bracket

V(x) = 7(5x - 2x^2) - 2x(5x - 2x^2)

V(x) = 35x - 14x^2 - 10x^2 + 4x^3

V(x) = 35x - 24x^2 + 4x^3

V(x) = 4x^3  - 24x^2+35x

Having a hard time solving this​
Pepsi [2]

Answer:

T=-13

Step-by-step explanation:

Simplifying

5t + 12 = 4t + -1

Reorder the terms:

12 + 5t = 4t + -1

Reorder the terms:

12 + 5t = -1 + 4t

Solving

12 + 5t = -1 + 4t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-4t' to each side of the equation.

12 + 5t + -4t = -1 + 4t + -4t

Combine like terms: 5t + -4t = 1t

12 + 1t = -1 + 4t + -4t

Combine like terms: 4t + -4t = 0

12 + 1t = -1 + 0

12 + 1t = -1

Add '-12' to each side of the equation.

12 + -12 + 1t = -1 + -12

Combine like terms: 12 + -12 = 0

0 + 1t = -1 + -12

1t = -1 + -12

Combine like terms: -1 + -12 = -13

1t = -13

Divide each side by '1'.

t = -13

Simplifying

t = -13
