Jim is enclosing a rectangular garden with 170 feet of fencing. The length of the garden is 10 feet more than twice it’s width,

Darina [25.2K]

Answer:

$1,500\ ft^2$

Step-by-step explanation:

Let

L ----> the length of the rectangular garden in feet

w ---> the width of the rectangular garden in feet

step 1

Find the width

we know that

The perimeter of the rectangular garden is

$P=2(L+W)$

$P=170\ ft$

$170=2(L+W)$

Simplify

$85=(L+W)$ ----> equation A

$L=2W+10$ ----> equation B

substitute equation B in equation A and solve for W

$85=(2W+10+W)$

$85-10=3W$

$3W=75$

$W=25\ ft$

Find the value of L

$L=2(25)+10=60\ ft$

step 2

Find the area

we know that

The area of the rectangular garden is

$A=(LW)$

substitute the values

$A=(60)(25)=1,500\ ft^2$

3(v + 2) + 4 = 13<br> HELP ME!!

Zolol [24]

3(v + 2) + 4 = 13

Mutiply the bracket by 3

(3)(v)= 3v

(3)(2)= 6

3v+6+4= 13

3v+10=13

Move +10 to the other side

Sign changes from +10 to -10

3v+10-10= 13-10

3v= 13-10

3v= 3

divide both sides by 3

3v/3= 3/3

v= 1

Answer : v= 1
