Answer:

x = 29

Step-by-step explanation:

The angles are corresponding angles and corresponding angles are equal when the lines are parallel

3x+17 = 4x-12

Subtract 3x from each side

3x+17-3x = 4x-12-3x

17 = x-12

Add 12 to each side

17+12 = x-12+12

29 =x

Answer:

D. 29

Step-by-step explanation:

If you plug in 29 in the missing values for L1 and L2, you get

L1 = 3(29) + 17 = 104

L2 = 4(29) - 12 = 104

I know I am correct because since both L1 and L2 are parallel and T in cutting them, I know that they are both going to be the same degrees, 104.

So, your answer would be D. 29

Hope the helps! :)

Find the perimeter of squared garden if its area is 1369m2

irina [24]

Answer:

the perimeter is of 148 m

Step-by-step explanation:

the perimeter is the sum of all sides so an square has all sides equal so we have

$P = x+x+x+x = 4x$

and the area is

$A=x^2=1369m^2$

so we find x

$\sqrt{x^2}=\sqrt{1369}\\\\x=37$

and now the perimeter

$P=4x\\\\P=4(37)\\\\P=148$

Math help asap 12,14,16,18,22 show work help asap assig 4

svetoff [14.1K]

Answer: see below

Step-by-step explanation:

12) 2(x + 4) = 8

÷2 ÷2

x + 4 = 4

-4 -4

$\large\boxed{x=0}$

14) 4w - 2(1 - w) = -38

4w -2 + 2w = -38

(4w + 2w) - 2 = -38

6w - 2 = -38

+2 +2

6w = -36

÷6 ÷6

$\large\boxed{w=6}$

16) 10(1 - 2y) = -5(2y - 1)

10 - 20y = -10y + 5

+20y +20y

10 = 10y + 5

-5 -5

5 = 10y

÷10 ÷10

$\large\boxed{\dfrac{1}{2}=y}$

$18)\quad s=\dfrac{1}{2}gt^2\\\\\\.\qquad (2)s=(2)\dfrac{1}{2}gt^2\quad \rightarrow \quad 2s=gt^2\\\\\\.\qquad \dfrac{2s}{t^2}=\dfrac{gt^2}{t^2}\qquad \rightarrow \qquad\large\boxed{\dfrac{2s}{t^2}=g}$

$22)\quad V=\pi r^2h\\\\\\.\qquad \dfrac{V}{\pi r^2}=\dfrac{\pi r^2h}{\pi r^2}\qquad \rightarrow \qquad \large\boxed{\dfrac{V}{\pi r^2}=h}$

-12x - 12y = 4 3x + 3y = 0

Svetradugi [14.3K]

Answer:

no Solution

Step-by-step explanation:

-12x-12y=4\\ 3x+3y=0

12x-12y=4

add 12y to both sides

12x-12y+12y=4+12y

divid both sides by -12

\frac{-12x}{-12}=\frac{4}{-12}+\frac{12y}{-12}

simplfy

x=-\frac{1+3y}{3}

\mathrm{Substitute\:}x=-\frac{1+3y}{3}

\begin{bmatrix}3\left(-\frac{1+3y}{3}\right)+3y=0\end{bmatrix}

\begin{bmatrix}-1=0\end{bmatrix}
