MRL 1.3 - Solving Equations with Var on Both Sides

What type of units are used to measure perimeter?

• Linear units

• Square units

• Cubic units

• Angular units

What is the formula for finding the perimeter P of a rectangle with length l and width w?

• P = l + w

• P = 2l + 2w

• P = lw

• P = l - w

What is the formula for finding the area A of a rectangle with length l and width w?

• A = l + w

• A = 2l + 2w

• A = lw

• A = l - w

How do you find the perimeter and area of a composite figure?

• Perimeter is the sum of all sides, and area is found by multiplying length and width.

• Perimeter is found by dividing the figure into equal parts, and area is found by adding all the parts together.

• Perimeter is found by subtracting the length from the width, and area is found by dividing the figure into equal parts.

• Perimeter is the sum of all sides, and area is found in parts and then added together.

What are the variable terms in the expression 5x - 2 - 9x + y + 4?

• 5x, -2, 4

• -2, 4

• 5x, -9x, y

• 5x, -2, 9x, y, 4

What are the constant terms in the expression 5x - 2 - 9x + y + 4?

• 5x, -9x, y

• -2, 4

• 5x, -2, 9x, y, 4

• 5,-2,-9,1,4

How do you know when an equation has no solution?

• When the equation has a false statement after solving normally.

• When the equation has an equivalent equation that is true for all values of the variable.

• When the equation has an equivalent equation that is not true for any value of the variable.

• When the equation has a true statement after solving normally.

What is the formula for the circumference C of a circle?

• C = πr

• C = 2πr

• C = πr^2

• C = 2πr^2

How do you solve the equation x + 5 = 3x + 1?

• Add x to both sides, add 1 to both sides, and then divide both sides by 4.

• Subtract x from both sides, subtract 1 from both sides, and then multiply both sides by 4.

• Add x to both sides, subtract 1 from both sides, and then divide both sides by 4.

• Subtract x from both sides, subtract 1 to both sides, and then divide both sides by 4.
