Rectangle with a length of 96 inches and width of 60 inches. A rug maker wants to increase each dimension by a different amount.

mr Goodwill [35]

Answer:

The perimeter of the new rectangle in simplified expression can be given as:

$2l+2w+312$

Step-by-step explanation:

The question is incomplete.

The actual question should be:

A rug maker is using a patter that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in inches of the length and width. write and simplify an expression for the perimeter of the new pattern.

Solution:

Original length of the rectangular pattern = 96 inches

Original width of the rectangular pattern = 60 inches

Let increase in length be = $l$ inches

New length of rectangle = $(96+l)$ inches

Let increase in width be = $w$ inches

New width of rectangle = $(60+w)$ inches

The perimeter of a rectangle is given by :

⇒ $2(length+width)$

Substituting the new length and width of the triangle.

⇒ $2(96+l+60+w)$

Simplifying.

⇒ $2(l+w+156)$

Using distribution.

⇒ $2l+2w+312$

Thus, the perimeter of the new rectangle in simplified expression can be given as:

$2l+2w+312$

Can somebody please help with this?

Kay [80]

Answer:

A. 2.9π(9²)

Step-by-step explanation:

You are expected to know that the area of a circle is given by the formula ...

A = πr²

and that r in the formula represents the radius of the circle, half the diameter.

The area of the circular base of the cylinder is the area of a circle with a radius of 9 feet. It will be ...

A = π(9²)

When that is multiplied by the height of the cylinder to find its volume, you have ...

V = Bh

V = (π(9²))(2.9)

This can be rearranged to match the form in answer choice A:

2.9π(9)²

I need help with this

alexira [117]

Answer:

g(x)=log(x+4)

Step-by-step explanation:

Here the parent function is f(x)=log x. The function has y intercept as 0 at x=1 .

If we observe the translated function we will observe that , the y intercept of new function is 0 at x=-3. Hence the function is moving ahead of the parent function by 4 units and reaches the y intercept being 0.

If we graph

g(X)= log X

the y intercept will be at (1,0)

X = 1 , Y =0

at X=1 , x = -3 or x = X-4

or X=x+4

Hence

new function will be g(x)=log ( x+4)

decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring. −b b2 − 4ac 2a u

Romashka [77]

Answer:

Step-by-step explanation:

A quadratic equation can be factorised if and only if there are rational roots.

For any quadratic equation the discriminant decides about the nature of roots.

Thus only if the discriminant is a perfect square we can have rational roots and in this case only factorization is possible.

In the given equation

$2x^2+ 7x+ 3 = 0\\a=2, b=7, c=3\\b^2-4ac = 1$

Since 1 is a perfect square we can factor and solve

$2x^2 +7x +3 = 0\\(2x+1)(x+3)=0\\x=-1/2 or x = -3$

Two third of a number is 30. find the number

liraira [26]

Answer:

The number is 45

Step-by-step explanation:

Let number = x

2/3 x = 30

x = 30/2/3

x = 30×3/2

x = 90/2 = 45

The number is 45

2/3 ×45= 90/3 = 30
