15 points+brainliest!! please help asap, this is due tonight please!!
Masteriza [31]

Answer:

x=\sqrt{13}

Step-by-step explanation:

Base of the isosceles triangle = 4

Perpendicular of the triangle = 3

In an isosceles triangle , a perpendicular bisects a base equally. So, here the isosceles triangle consist of 2 right angled triangles.

In that right angled triangles,

Base = 4/2 = 2 (∵ A perpendicular divides a base into 2 equal parts. )

Perpendicular = 3

Hypotenuse = x

So , according to Pythagorean Theorem ,

Hypotenuse = \sqrt{Base^2 + Perpendicular^2}

Using all the values above into the formula gives :-

x =\sqrt{2^2 + 3^2} = \sqrt{4+9} =\sqrt{13}

It’s a triangle
s
r t

rs= 2x+10 and st= x-4

the sides are equal so equal them together then solve

2x+10=x-4
+ 4 +4
2x+14=x

you got x alone so x=2x+14

now you plug in 2x+14 in for the x in rs and st

rs= 2(2x+14)+10
4x+28+10
4x+38

st= (2x+14)-4
2x+14-4
2x-10

Anastaziya [24]

9514 1404 393

Answer:

  g(x) = √(x -5) +7

Step-by-step explanation:

To translate the graph of f(x) by h units horizontally and k units vertically, the function is transformed to ...

  g(x) = f(x -h) +k

To translate f(x) = √x by 5 units horizontally and 7 units vertically, the function is transformed to ...

  g(x) = √(x -5) +7
