Hii can someone pls help me, I’m not sure what the answer is

(√10)*a

Step-by-step explanation:

In a triangle rectangle, we have 3 sides, in this case, the shorter base, a, the longer base, b and the hypotenuse h.

And the hypotenuse can be found with the Pythagorean's theorem.

a^2 + b^2 = h^2

now, we know that b = 3a, then we can replace it in the above equation:

a^2 + (3*a)^2 = h^2

a^2 + 9*a^2 = h^2

10*a^2 = h^2

now we can apply the square root to both sides and get:

√(10*a^2) = √h^2

(√10)*a = h

Then we have found the length of the hypotenuse in terms of the shorter side a.

The length of the hypotenuse is √(10)*a

Step-by-step explanation:

Remember the Pythagorean theorem.

If b is the larger base, and a the shorter base, and H is the hypotenuse:

a^2 + b^2 = H^2

now, we know that b = 3*a.

(3*a)^2 + a^2 = H^2

10*a^2 = H^2

√(10)*a = H

Then we have the length of the hypotenuse in terms of the shorter base, B.

[tex](55,23)\\\\(-35,-13)[/tex]

Step-by-step explanation:

The given points are written in (x,y) form. Substitute the given value of a point into the given equation:

[tex](55,y)\\\\5y-2x=5\\\\5y-2(55)=5[/tex]

Solve the equation for the value of y when x is 55.

Simplify multiplication:

[tex]5y-110=5[/tex]

Add 110 to both sides:

[tex]5y-110+110=5+110\\\\5y=115[/tex]

Isolate y. Divide both sides by 5:

[tex]\frac{5y}{5} =\frac{115}{5} \\\\y=23\\\\(55,23)[/tex]

When y is 55, x is 23.

Insert the value into the equation:

[tex](x,-13)\\\\5y-2x=5\\\\5(-13)-2x=5[/tex]

Solve for x when y is -13.

Simplify multiplication:

[tex]-65-2x=5[/tex]

Add 65 to both sides:

[tex]-65+65-2x=5+65\\\\-2x=70[/tex]

Divide both sides by 2:

[tex]\frac{-2x}{2}=\frac{70}{2} \\\\-x=35[/tex]

Multiply both sides by -1:

[tex]-1(-x)=-1(35)\\\\x=-35\\\\(-35,-13)[/tex]

When y is -13, x is -35.

:Done

i think its right!!

Step-by-step explanation:

I believe the answer is B but I’m not for sure

I think it's the first one, cause in the first step he put +2 instead of -2 on the left side. I hope that helped

The answer is a smart asain girl they do all the work for you it’s great you should get one o
