3{[9(x - 2) + 7] - 2[4(x + 5) - 36]}

= 3[9x - 18 + 7 - 2(4x + 20 - 36)]

= 3(9x - 11 - 8x - 40 + 72)

= 3(x + 21)

= 3x + 63

The perimeter of a rectangular garden is 110ft. The length is 5 ft greater than the width. Find the length and width.

tigry1 [53]

P = perimeter

L = length

W = width

Formula for the perimeter of a rectangle = L + L + W + W or P = 2L + 2W

You know:

P = 110ft

L = W + 5 [length is 5ft greater than the width]

So plug this into the formula:

P = 2L + 2W Substitute/plug in (W + 5) for L

110 = 2(W + 5) + 2W Distribute/multiply 2 into (W + 5)

110 = (2)W + (2)5 + 2W

110 = 2W + 10 + 2W Combine like terms (2W + 2W)

110 = 4W + 10 Subtract 10 on both sides

110 - 10 = 4W + 10 - 10

100 = 4W Divide 4 on both sides to get "W" by itself

$\frac{100}{4}=\frac{4W}{4}$

25 = W Now that you know the width, plug it into the equation for length

L = W + 5 Plug in 25 for W

L = 25 + 5

L = 30

L = 30 ft

W = 25 ft

PROOF

P = 2L + 2W

110 = 2(30) + 2(25)

110 = 60 + 50

110 = 110

Figure ABCD is a kite. The area of ABCD is 48 square units. The length of line segment BD is 8 units. What is the length of AC?

astra-53 [7]

The area of a kite:
A = d1 * d2 / 2
d1 = BD = 8 units
48 = 8 * AC / 2
48 * 2 = 8 AC
96 = 8 AC
AC = 96 : 8 = 12
Answer: D ) 12 units

Anyone know how to solve this? I know the answers for j and g but I need help finding h, f and i!!!!!!! PLS HELP TY! (SEE ATTACH

Juliette [100K]

Step-by-step explanation:

RISE/RUN is an important rule...

f = $\frac{50}{3}$ = around 16.7 (3.s.f)

h = $\frac{(70-50)}{(6-4)}$ or $\frac{20}{2}$ = 10

i = $\frac{30}{1}$ = 30
