Question

Look yall i got 10 math questions if you get all ten right brainlliest so if yall could help a man out here it would be great

here they are

A.
if a=b,then
`a^(2) =b^(2)`
B
if
`a\leq b then a^(2) \leq b^(2)`
C

`if a\geq b then a^(2) \geq b^(2)`
D

`if a \\eq b then a^(2) \\eq b^(2)`

2.)Solve for x.

`√(x-2) =9`
A.
11
B.
20
C.
83
D
no solution

3.)The length of a side of a square is
`\sqrt{x^(2)-4 }` If the area of the square is 12, find x.
A.
16
B.
4
C.
12
D.

`√(148)`

4).Solve for x.

`5x^(2) +3=-122`

A.
no solution
B.
–5
C.
±5
D.

5.)solve for x
`x^(2) +5=30`

A.
±25
B.

`√(35)`
C.
±5
D.

6.)The acceleration of an object can be described by the equation

B.

`t=\sqrt{(a)/(15) }`
C.

`t=\sqrt{(30)/(a) }`
D.

`t=2\sqrt{(30)/(a) }`

7.)The acceleration of an object can be described by the equation
`a=\sqrt{(2d)/(t²) }` , where a is acceleration, d is the distance, and t is time. Suppose an object accelerates at a rate of 5 meters per second squared. Which of the following equations relates the time of the acceleration to the distance?
A.

`t=√(10d)`
B.

`t=√(2d)`
C.

`t=\sqrt{(5d)/(2) }`

no solution

9.)Solve for x:
`√(3x-2)=2`

A.
2
B.

`-(2)/(3)`
C.
–2
D.
no solution

10.)What is the first step to solve the equation
`x^(2) -3=15`
A.
Take the square root of
`x^(2)`, 3, and 15.
B.
Square 15.
C.
Add 3 to both sides of the equation.
D.
Add 1 to both sides of the equation.

can yall help a brother out im in deep sh|t if i dont pass so if your gunna do it do it right thank yall for helpen me out oh and i already tried to look em up so that dont work

Answer 1

number 2. is A I think number 8. is -2 or 2 it might be between those two

2.explanation: 11-2=9
