Please help! I don’t know how to do it!!

A gallon of paint will cover approximately 350 square feet and artist wants to paint all the outside surfaces of a cube measurin

Gelneren [198K]

Assuming that the artist wants to paint 6 sides of the cube, the formula to count the surface area of the cube would be: 6* edge length^2. If the edge length is 10 feet, then the area would be:
area= 6*edge length^2
area= 6* 10^2 feet
area= 6*100feet^2= 600 feet^2

If one gallon of paint can be used for 350 feet^2, the amount of paint needed would be: 600feet^2/ (350ft^2/ gallon)= 1.71 gallon

Rewrite the given equation in standard form. f(x) = 5x2

pickupchik [31]

Answer:

a = 5, b = -3 and c =1

Step-by-step explanation:

The standard form of a quadratic equation is expressed as;

f(x) = ax² + bx + c

Given the expression

f(x) = 5x² = 3x - 1

f(x) = 5x² - 3x + 1

Comparing with the general formula;

ax² = 5x²

a = 5

bx = -3x

b = -3

c = 1

Hence a = 5, b = -3 and c =1

Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5.

amm1812

The equation of the line in standard form is 3x - 5y = 26

Step-by-step explanation:

Let us revise the forms of the linear equation

The slope intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept
The point-slope form is $y-y_{1}=m(x-x_{1})$ , where m is the slope of the line and $(x_{1},y_{1})$ is a point on the line
The standard form is Ax + By = C, where A, B, and C are constant
The general form is Ax + By + C = 0, where A, B, and C are integers
