What is a scalene triangle?

2 answers:

5 0

A scalene triangle is a triangle with no sides equal. Consequently, all the angles are not equal as well.

When all the sides are equal, it's called an equilateral triangle.
When two sides are equal, it's called an isosceles triangle.

A scalene triangle is simply a triangle with no congruent sides. This just means that no sides are equal and no angles are equal.

(6h + 8) - (3h + 2) = 15<br> PLEASE HELP I ALSO NEED TO SHOW WORK

Anestetic [448]

Answer:

$h=3$

Step-by-step explanation:

So we have the equation:

$(6h+8)-(3h+2)=15$

First, let's distribute the negative:

$(6h+8)+(-3h-2)=15$

Combine like terms:

$(6h-3h)+(8-2)=15$

Subtract or add:

$3h+6=15$

Subtract 6 from both sides:

$3h=9$

Divide both sides by 3:

$h=3$

And we're done!

What is f(g(x)) for x > 5?

mel-nik [20]

Answer:

$\large\boxed{B.\ 4x^2-41x+105}$

Step-by-step explanation:

$f(x)=4x-\sqrt{x}\\\\g(x)=(x-5)^2\\\\f(g(x))\to\text{put}\ x=(x-5)^2\ \text{to}\ f(x):\\\\f(g(x))=f\bigg((x-5)^2\bigg)=4(x-5)^2-\sqrt{(x-5)^2}\\\\\text{use}\\(a-b)^2=a^2-2ab+b^2\\\sqrt{x^2}=|x|\\\\f(g(x)=4(x^2-2(x)(5)+5^2)-|x-5|\\\\x>5,\ \text{therefore}\ x-5>0\to|x-5|=x-5\\\\f(g(x))=4(x^2-10x+25)-(x-5)\\\\\text{use the distributive property:}\ a(b+c)=ab+ac\\\\f(g(x))=(4)(x^2)+(4)(-10x)+(4)(25)-x-(-5)\\\\f(g(x))=4x^2-40x+100-x+5\\\\\text{combine like terms}\\\\f(g(x))=4x^2+(-40x-x)+(100+5)\\\\f(g(x))=4x^2-41x+105$
