Answer:

0x = 0y

0x = 2y

x = 2y/0 = 0

2x = 2y

x = 2y/2 = y

4x = 3y

x = 3y/4

Answer:

4448 feet²

Step-by-step explanation:

Using the formula $A = 2((l)x(w) + (l)x(h) + (w)x(h))$ we can take the length, width and height and plug them in. $A = 2(44x21 + 44x20 + 21x20)$ , solving this equation we get $4448 feet^{2}$ .

Find the value of x

iVinArrow [24]

Answer:

x = 121

Step-by-step explanation:

Let the measure of the altitude of the given triangle be h units.

By geometric mean theorem:

$h = \sqrt{23 \times x} \\ \\ h = \sqrt{23x} \\ \\ now \: by \: pythagors \: theorem \\ \\ {(x + 11)}^{2} = {h}^{2} + {x}^{2} \\ \\ \cancel{{x}^{2}} + 22x + 121 = {( \sqrt{23x} )}^{2} + \cancel{{x}^{2}} \\ \\ 22x + 121 = 23x \\ \\ 22x - 23x = - 121 \\ \\ - x = - 121 \\ \\ x = 121$

Solve x;<br> x- 2 (divided by) -8 = 0<br><br> --Please Help! Due in for tomorrow! Xx

Yanka [14]

X=2
you multiply by 8 on both sides. so that your equation now looks like x-2=0
then you will add by 2 on both sides.
x=2

Eight angles of a nonagon measure 1389, 154º. 145°, 132°, 148°, 143,

PIT_PIT [208]

Answer:

103°

Step-by-step explanation:

The total angle in a nonagon is 1260. To get the missing angle, we add up all the given angle together and subtract it from 1260.

138 + 154º + 145° + 132° + 148° + 143 + 147 + 150 = 1157

1260 - 1157 = 103

Therefore, the missing angle is 103°
