Answer:
15
Step-by-step explanation:
2(2) - 18 = -14 |-14| = 14
3(2) -7 = -1 |-1| = 1
14+1=15
Answer:
$1250
Step-by-step explanation:
6 1/4 × 4 = 25
25 × 50 = cost
Cost = $1250
Answer:3
Step-by-step explanation:
The solution of the given equations is: (-1.5, 1.5)
Step-by-step explanation:
Linear equation usually represents a straight line. When a system of two liner equations is given, the point of intersection of lines represented by both equations is the solution of the system of equations.
We will plot the lines of both equations and find their point of intersection (Picture Attached)
We can see in the picture that two lines intersect at (-1.5, 1.5)
Hence,
The solution of the given equations is: (-1.5, 1.5)

Answer:
Part A:
(2x+7)(5x+9)
=(2x+7)(5x+9)
=(2x)(5x)+(2x)(9)+(7)(5x)+(7)(9)
=10x2+18x+35x+63
=10x2+53x+63
A)
The formula for determining the area of a rectangle is given as
Area = length × width
Given that the length and width are (2x + 6) units and (5x + 3) units, the expression for the area is
(2x + 6)(5x + 3) = 10x² + 6x + 30x + 18
Area = 10x² + 36x + 18
B)
The degree is 2 because the highest power of the terms is 2. It is classified as a trinomial because it has 3 terms.
C) it is closed under multiplication. the exponents in the polynomials are whole numbers(2 and 1). The whole numbers are closed under addition, which means that the new exponents formed are also whole numbers. The exponents were whole numbers before multiplication and doesn't change after multiplication.
