Write an expression for the calculation double 7, multiply 3 and 1, and then subtract the second number from the first number

The correct expression is:

(2×7)-(3×1)

Explanation:

The expression for doubling 7 is multiplying 7 by 2, or 2×7.

The expression for the product of 3 and 1 is 3×1.

Subtracting the second number from the first one would be writing the first number first, then minus the second: (2×7)-(3×1)

answer: b.36 feet

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
