The width of a rectangle is represented by 5 + 2y. The length is twice as long as the width. What is the perimeter of the rectan
Lilit [14]
The answer is 12y+30.
Twice the width would be 10+4y, so the length is 10+4y.
To find the perimeter, we can do 2(5+2y) + 2(10+4y).
That equals 10+4y+20+8y.
Which, equals 12y+30.

Hi May I know how to solve this question with step by step explanation please
Anuta_ua [19.1K]

Answer:

a = 1, b = - 2

Step-by-step explanation:

The points that lie on the curve and straight line satisfy the corresponding equations.

Substitute the points into their corresponding equations, that is

(1, - 1 ) → - a = 1² + b = 1 + b ( multiply both sides by - 1 )

a = - 1 - b → (1)

(3, 3 ) → \frac{-3b}{2} = \frac{3}{a} ( cross- multiply )

- 3ab = 6 ( divide both sides by - 3 )

ab = - 2 → (2)

Substitute a = - 1 - b into (2)

(- 1 - b)b = - 2 , distribute left side

- b - b² = - 2 ( multiply through by - 1 )

b² + b = 2 ( subtract 2 from both sides )

b² + b - 2 = 0 ← in standard form

(b + 2)(b - 1) = 0 ← in factored form

Equate each factor to zero and solve for b

b + 2 = 0 ⇒ b = - 2

b - 1 = 0 ⇒ b = 1

Substitute these values into (1) for corresponding values of a

b = - 2 : a = - 1 - (- 2) = - 1 + 2 = 1

b = 1 : a = - 1 - 1 = - 2

Thus a = - 2, b = 1 or a = 1, b = - 2

Given that a > b then a = 1, b = - 2

Write and solve an equation to find the complement of a 42 degree angle. tell what the variable represents.
EastWind [94]
The complememtn is the angle that adds to the angle to get 90

so

the complement of angle a is b if
a+b=90

so

the comlmement of a 42 degree angle is
42+complement=90
complmement=c
42+c=90
minus 42 both sides
c=48

the measure of the complement is 48 degrees
c is the complement
