Can somebody help me with this question
Alexus [3.1K]
We start with:

y=2x-15
y=5x

Now, we have a perfectly set-up variable we can get rid of: <em>y.</em>

But we need to make either the top or bottom equation negative, so for simplicity, let's make the bottom one negative.

y=2x-15
(-y)=(-5x)

Now simplify.

-3x-15=0

Add 3x on both sides.

3x=15

Divide by 3 on both sides.

x=5

If x is 32 mm what’s the area of the triangle
Ksju [112]

Answer:

4608*sqrt(3)

Step-by-step explanation:

x + 2x = 3x, so 3x is the height of the triangle.  This is a 90-60-30 triangle so the base would be 3x*sqrt(3).  To find the area, we can multiply the base with the height and divide by two, so it would be (3x)(3x*sqrt(3))/2 or (9/2)x^2 * sqrt(3).  x = 32, and plugging this into the equation gets us to (9/2)32^2 * sqrt(3), which is 4608*sqrt(3).
