Answer:

x= 70

Step-by-step explanation:

AB= 180 so u add 20+ 50 and then substract that to 180 which leaves you with 110. The angles are the same on both sides so the other angle is also 110, leaving x to be 70°

hope this is correct lol :)

Solve for x, given the equation Square root of x plus 9 − 4 = 1.

Daniel [21]

ANSWER

The value of x is
$16.$

EXPLANATION

We want to solve the equation,

$\sqrt{x + 9} - 4 = 1$

The first step is to add 4 to both sides of the equation to obtain,

$\sqrt{x + 9} = 1 + 4$

We simplify the right hand side to obtain,

$\sqrt{x + 9} = 5$

We now square both sides of the equation to obtain,

$(\sqrt{x + 9} ) ^{2} = {5}^{2}$

This simplifies to

$x + 9= 25$

We solve for x to obtain,

$x = 25 - 9$

This implies that,

$x = 16$

JulijaS [17]

Answer:

Area = 294 cm^2

Volume = 343 cm^3

Step-by-step explanation:

Simply plug in s = 7 into the given equations.

$6s^{2} = 6*7^{2} = 294 cm^{2}$

$s^{3} = 7^{3} = 343 cm^{3}$
