Find the value of x for which the lines r and s are parallel. answers: 13 47 48 12
juin [17]

Answer:

x=12

Step-by-step explanation:

142 and 3x+2 are supplementary angles when the lines are parallel

142+ 3x+2 = 180

Combine like terms

144+3x= 180

Subtract 144 from each side

144+3x-144=180-144

3x=36

Divide by 3

3x/3 = 36/3

x =12

What is the solution to the equation 3 + 4 sqr root 4y = 4?
lawyer [7]

Answer:

1/64

Step-by-step explanation:

Given the expression

3+4√4y = 4

4√4y = 4-3

4√4y = 1

√4y = 1/4

Square both sides

(√4y)²= (1/4)²

4y = 1/16

y = 1/16 * 1/4

y = 1/64

Hence the value of y is 1/64

Please help !!!! picture shown
Serhud [2]
\sqrt{10 x^{2} }·\sqrt{5x}=\sqrt{50 x^{3} }. This can be simplified to 5x\sqrt{2x}, because √50 simplifies to 5√2 (since 5x5x2 equals 50) and the square root sign takes x² from x³ and turns it into just x.
