X^2+8x+15 is the area

because x+5 = length
and x +3 = width

(x+5)(x+3) =
x^2+3x+5x+15 =
x^2+8x+15 (area)

My homework is Identify the terms, like terms, coefficients, and constants in each expression and I need the answers to n+5n, 12
AysviL [449]

Step-by-step explanation:

A term is a number, a variable, or a constant multiplied by a variable or variables.

Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different.

A coefficient is a multiplicative factor in some term of a polynomial (expression).

Constant is a term in the algebraic expression that contain only number.

n + 5n = n + 5n + 0

terms: n, 5n

like terms: n, 5n

coefficients: 1, 5

constant: 0

simplified form: n + 5n = 6n

term: 6n

coefficient: 6

constant: 0

=======================

12c - c = 12c - c + 0

terms: 12c, -c

like terms: 12c, -c

coefficients: 12, -1

constant: 0

simplified form: 12c - c = 11c

term: 11c

coefficient: 11

constant: 0

========================

-4j - 1 - 4j + 6

terms: -4j, -1, -4j, 6

like terms: -4j, -4j and -1, 6

coefficients: -4, -4

constants: -1, 6

simplified form: -4j - 1 - 4j + 6 = (-4j - 4j) + (-1 + 6) = -8j + 5

term: -8j, 5

coefficient: -8

constant: 5

What is the solution to the inequality |2n+5| > 1 ?
Serhud [2]

Answer:

n > -2                 or      n < -3

Step-by-step explanation:

|2n+5| > 1

We have two solutions one positive and one negative.  Remember to flip the inequality symbol for the negative

2n+5 > 1         or 2n+5 < -1

Subtract 5 from each side

2n+5-5 > 1-5         2n+5 -5 < -1 -5

2n >-4                    2n < -6

Divide by 2

2n/2 > -4/2             2n/2 < -6/2

n > -2                 or       n < -3

A small town has two local high schools. High School A currently has 750 students and is projected to grow by 45 students each y
PtichkaEL [24]

Answer: A=750 +75*t

B=900 +25*t

There would be 975 students in each high school in year 3 when they are expected to have the same number of students.

Step-by-step explanation:

A = B

750 +75*t=900 + 25*t

Solving:

75*t -25*t= 900 - 750

50*t= 150

t=3

This indicates that in year 3 both High Schools are projected to have the same number of students. To get that amount, you simply replace this value in the expressions:

A=750 +75*t= 750 +75*3= 975

B=900 + 25*t=900 + 25*3= 975

There would be 975 students in each high school in year 3 when they are expected to have the same number of students.
