The length of a rectangle is 4 more than twice the width. The perimeter is 74 feet. Find the length and width of the rectangle.

mafiozo [28]

(2*length)+(2*width)=perimeter
length=4+2w
(2(4+2w))+(2(w))=74
74=(8+4w)+(2w)
74=6w+8
66=6w
w=11
length=4+2(11)
l=4+22
l=26

krek1111 [17]

Answer:

72 cans

Step-by-step explanation:

step 1

Find the number of people

we know that

She ordered 1 pizza for every 4 people

using proportion

Find out the number of people for 6 pizzas

$\frac{1}{4}=\frac{6}{x}\\\\x=24\ people$

step 2

Find the number of cans ordered

we know that

Charissa ordered 3 cans of lemonade for each person

using proportion

Find out the number of cans of lemonade she ordered for 24 people

$\frac{3}{1}=\frac{x}{24}\\\\x=24(3)\\\\x=72\ cans$

If the product of two positive consecutive odd integers is 63, what’s the larger number ?

myrzilka [38]

For this case we have:

$x$ : Let the variable representing the first odd number

$x + 2$ : Let the variable representing the consecutive odd number at x.

According to the statement we have:

$x (x + 2) = 63\\x ^ 2 + 2x = 63\\x ^ 2 + 2x-63 = 0$

We found the solution by factoring:

We look for two numbers that, when multiplied, result in -63 and when added, result in 2. These numbers are +9 and -7.

$9-7 = 2\\9 * (-7) = -63$

Thus, we have:

$(x + 9) (x-7) = 0$

Therefore the solutions are:

$x_ {1} = - 9\\x_ {2} = 7$

We choose the positive value, so we have:

$x = 7\\x + 2 = 7 + 2 = 9$

Answer:

The largest number is 9
