Question:

Solve the following problem using the order of operations: ( 20 ÷ 4 ) + (( 10 + 3 ) x 15) =

Erica P.

Answer:

Following order of operations means first working out problems within the parentheses, then exponents, if there are any, followed by multiplication, division, addition, and subtraction. Solving in the parentheses first: ( 20 ÷ 4 )= 5 ; ( 10 + 3 )= 13 The full equation is now: 5 + ( (13) x 15) = Next, multiply: ( (13) x 15) = 195 Finally, add: 5 + ( 195) = 200

Question:

Multiply the binomials using the FOIL method: ( 5X - 3 ) ( X + 2 )

Erica P.

Answer:

To answer this question, you must use the FOIL method, or (First, Outside, Inside, Last). This means to start by multiplying the first term in the first set of parentheses with the first term in the second set of parentheses: ( 5X ) ( X ) = 5X² Then, multiply the first term in the first set of parentheses with the second term in the second set of parentheses: ( 5X ) ( 2 ) = 10X Next, multiply the second term in the first set of parentheses with the first term in the second set of parentheses: ( - 3 ) ( X ) = - 3X Third, multiply the second term in the first set of parentheses with the second term in the second set of parentheses: ( - 3 ) ( 2 ) = -6 Fourth, add all of your answers together: ( 5X² ) + ( 10X ) + ( - 3X ) + ( - 6 ) Lastly, simplify by combining like terms: 5X² + 7X - 6
