What is the middle term of the product of (x - 4)(x - 3)? -x x -7x

Answers

Answer 1

Answer:

Answer:

The middle term of the equation is (x - 4)(x - 3) is -7x .

Step-by-step explanation:

As given the expression in the question be as follow .

= (x - 4)(x - 3)

First open the bracket and simplify the above terms .

= x × x - x × 3 - 4 × x -4 × -3

= x² -3x -4x + 12

= x² -7x + 12

Therefore the middle term of the equation is (x - 4)(x - 3) is -7x .

Answer 2

Answer:

x^2 - 4x - 3x + 12

= x^2 -7x +12

middle term= -7x

PLEASE HELP!Find the domain, period, range, and amplitude of the cosine function.

y = -6 cos 4x

A. domain = -1/2 ≤ x ≤ 1/2; period = 6; range:- -6 ≤ y ≤ 6; amplitude = 1/2
B. domain = all real numbers; period = π/2 ; range:- -6 ≤ y ≤ 6; amplitude = 6
C. domain = all real numbers; period = π/2 ; range: -6 ≤ y ≤ 6; amplitude = -6
D. domain = -1/2 ≤ x ≤ 1/2; period = 6π; range: -6 ≤ y ≤ 6 ; amplitude = 1/2

Answers

Domain is all real numbers because there is a y value for every x.
The amplitude is the absolute value of the constant of the outside: |-6| = 6
The range is that x is between the positive and negative amplitude: -6 ≤ y ≤ 6
The period is usually 2π, but here it is 2π/4, or π/2, as it goes up and down 4 times as fast as it would if it was just cos x.

1. Anne wants to join five pieces of paper together. She plans to use 3 rectangular pieces of the same size and 2 square pieces of the same size. The length of each rectangular piece is 3 1/2 feet. The width of each rectangular piece, w, is the same as the length of each square piece. The expression below can be used to find the total surface area of the five pieces of paper. Anne decides that the width, w, of the rectangular pieces should be 2 feet. What is the total surface area, in square feet, of all five pieces of paper?
