15x +10z because if you use the distributive property of multiplication,
 5 x 3x = 15x and 5 x 2z = 10z

Answer:

270

Step-by-step explanation:

The formula for finding the area of a triangle is <em>base · height ÷ 2, </em>or \frac{bh}{2}

After plugging in the numbers given to the formula, we find that the area of the triangle is 27.

Then to account for the length, we multiply the area of the triangle by 10.

This gets us to 270.

A linear function has a slope of 2 and passes through the point (0,6). What is the equation of the line?
pychu [463]
A linear function means you’re working with a line. Lines can be stated in slope-intercept form: y=mx+b.

To make it a linear function, you simply replace “y” with “f(x)” notation: f(x) = mx + b

The information you gave told you m=2 and b=6, since (0,b) is the y-intercept.

Putting that all together you have:
f(x) = 2x + 6
