X²+4x+4=25
x²+4x+4-25=0
x²+7x-3x-21=0
x(x+7)-3(x+7)=0
(x+7)×(x-3)=0
x+7=0
x-3=0

x=-7
x=3

so your answer is x=-7 x=3

2/3y - 2/5 = 5 and please show work Algebra

Travka [436]

2/3y-2/5=5

We move all terms to the left:

2/3y-2/5-(5)=0

Domain of the equation: 3y!=0

y!=0/3

y!=0

y∈R

determiningTheFunctionDomain

2/3y-5-2/5=0

We calculate fractions

There is no solution for this equation

1. The perimeter of a piece of paper is 18 cm.

OlgaM077 [116]

Answer:

a) length = 3 and width = 6

Area of the rectangle = 3 × 6 = 18 cm²

b) length = 7 and width = 2

Area of the rectangle = 7 × 2 = 14 cm²

c) length = 5 and width = 4

Area of the rectangle = 5× 4 = 20 cm²

Step-by-step explanation:

Step(i):-

Given perimeter of the paper = 18 cm

we know that the paper has a rectangle shape

The perimeter of the rectangle = 18 cm

2( l + w ) = 18

we choose length = 3 and width = 6

The perimeter of the rectangle = 2( 3+6) = 18 cm

Area of the rectangle = 3 × 6 = 18 cm²

we choose length = 7 and width = 2

The perimeter of the rectangle = 2( 7+2) = 18 cm

Area of the rectangle = 7 × 2 = 14 cm²

we choose length = 5 and width = 4

The perimeter of the rectangle = 2( 5+4) = 18 cm

Area of the rectangle = 5× 4 = 20 cm²
