The value of x determined algebraically given the total area of the rectangle is 1.5 inches
<h3>How to find area of a rectangle</h3>
Initial dimensions:
Length = 14 inches
Width = 10 inches
New dimensions:
Length = 14 + x
Width = 10 + x
Area = 320 square inches
Area of a rectangle = Length × Width
320 = (14 + x) × (10 + x)
320 = 14x × 10x
320 = 140x²
x² = 320/140
x² = 2.28571428571428
x = √2.28571428571428
x = 1.511857892036908908858066144936720243
Approximately,
x = 1.5

Answer:
£7,878
Step-by-step explanation:
she gets:
40p× 260 miles = 10,400p
she pays:
52 : 5.36= £9.70 per mile
260 x 9.70 = £2,522
to find out what she claimes more than she pays: 10,400 - 2,522 = 7,878
Y=10 and 3x+2y=3
X=-3 is NOT a function because it has multiple y values for one x value.
Y equals ten is a horizontal line, and passes the vertical line test, as does the third equation
Answer:
E
Step-by-step explanation:
if we decidedly factor this expression-
4x^2+4xy+y^2
= (2x)^2 + 2*2xy + y^2
= (2x + y)^2
as you can see it is a perfect square so it can be grouped into (2x+y)^2
hence your solution is option e
