Answer:

324 square feet

Step-by-step explanation:

Hello

The equation to find the area of ​​the rectangle is simply A = h * b. This means that the area of ​​a rectangle is equal to the product of its height (h) by its base (b), or of its length by its width,on the other hand the perimeter of the rectangle is the total sum of all its sides P=2L+2W

Step

find the value of w

Let

L=2w+3

w=w

P=2L+2W

P=2(2w+3)+2w

P=4W+6+2W

P=6W+6

we know the perimeter is 78 feet

78=6w+6

isolating W

78-6=6W

72/6=W

W=12

step 2

find the area

A=l*w

let

l=2w+3

l=2(12)+3

length =27

w=w=12

width =12

A=l*w

A=27 feet * 12 feet

A=324 square feet

Have a great day

Otrada [13]

Answer:

20 and 3/16

Step-by-step explanation:

Answer:

578×176=20316

Solution with Steps

578×176=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

57×178×6=96948

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 969 and 48 using

GCF(969,48) = 3

969÷348÷3=32316

The fraction

32316

is the same as

323÷16

Convert to a mixed number using

long division for 323 ÷ 16 = 20R3, so

32316=20316

Therefore:

578×176=20316

Solution by Formulas

Apply the fractions formula for multiplication, to

578×176

and solve

57×178×6

=96948

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(969,48) = 3

969÷348÷3=32316

Convert to a mixed number using

long division for 323 ÷ 16 = 20R3, so

32316=20316

Therefore:

578×176=20316

This is a continuous set of points in the coordinate plane. It can be, but is not always, straight.
castortr0y [4]

Answer:

Linear. While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).

Christine buys 7 hamburgers and 3 sodas for $27.95. Laura buys 5 hamburgers and 4 sodas for $23.40. How much does a hamburger co
Naddika [18.5K]
7h+3s=27.95 subtract 7h from both sides

3s=27.95-7h  divide both sides by 3

s=(27.95-7h)/3

Then we are told:

5h+4s=23.4,  using s found above makes this equation become:

5h+4(27.95-7h)/3=23.4  multiply both sides by 3

15h+4(27.95-7h=70.2  perform indicated multiplication on left side

15h+111.8-28h=70.2 combine like terms on left side

-13h+111.8=70.2 subtract 111.8 from both sides

-13h=-41.6  divide both sides by -13

h=$3.20
