The width and length of a rectangle (in feet)are consecutive odd integers. If the length is increased by 5 feet, the area of the

Tresset [83]

Original:
The width and length of a rectangle are consecutive odd integers
so W = x and L = x + 2

If the length is increased by 5 feet, then new L = x + 2 + 5 = x + 7

A = L x W
60 = (x + 7) x
60 = x^2 + 7x
x^2 + 7x - 60 = 0
(x - 5)(x + 12) = 0
x = 5 and x = -12

From here you have x = W = 5 ft and L = x + 2 = 5 + 2 = 7 feet

Area of original = 5 x 7 = 35

answer
the area of the original rectangle: 35 ft^2

In the blueprint for A rectangular balcony is 1 inch by 1.75 inches if the actual length is 7 feet what is the perimeter

Elenna [48]

Answer:

22 feet

Step-by-step explanation:

Given

In blue print,dimensions of rectangular balcony are, length(l)=1.75inch and breadth(b)=1inch
The actual length(L)=7 feet

To find the actual perimeter, we need the breadth of balcony(B)

The ratio of length to breadth in blue print must be equal to the ratio of actual length to breadth

⇒

$\frac{\text{length of rectangular balcony in blueprint}}{\text{breadth of rectangular balcony in blueprint}} =\frac{\text{length of rectangular balcony actually}}{\text{breadth of rectangular balcony actually}}$

$\frac{l}{b} =\frac{L}{B} \\B\times l=L \times b\\B= \frac{L \times b}{l}=\frac{7 \times 1}{1.75} =4$

Therefore Breadth actually=4 feet

⇒Perimeter

$=2\times(length+breadth)\\=2\times(7+4)\\=2\times(11)\\=22$

Therefore perimeter of rectangular balcony= 22 feet

Find the equivalent expression 11(3p+5x)+4x-x

Alex777 [14]

Hello there! :)

Answer:

=33p+58x

*The answer must have a positive sign.*

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, expanded form. Then you can also multiply from left too right.

$11(3p+5x)=33p+55x$

Next, rewrite the problem down.

$33p+55x+4x-x$

And finally, you add by the similar elements. Then you add by the numbers too.

$55x+4x-x=58x$

Final answer: → $33p+58x$

Hope this helps!

Thanks!

Have a great day!

The ratio of the side length of Square A to the side length of Square B is 4:9. The side length of Square A is 12 yards. What is

lubasha [3.4K]

A/B : 4/9 = 12/B
cross multiply
(4)(B) = (9)(12)
4B = 108
B = 108/4
B = 27

P = 4a...where a is the length of one side
P = 4(27)
P = 108 yds <=== perimeter of square B

3 Najid paid $10 000 income tax in a year. What was his salary that year?

marta [7]

Answer:

income tax=13% of total salary

Step-by-step explanation:

Here,

let salary be 'x'

Now,

13%of x = $10 000

13/100 × x = $10 000

13x = 1000000

x=10 00000/13

Therefore x =76,923.0769

His salary that year was 76,923.0769
