Hey I need help with this one question I don’t understand it

y= -x-6

Step-by-step explanation:

slope intercept is as follows

y=mx+b

where m is the slope and b is the y intercept (where the line crosses the y axis)

We can see that the x intercept is -6 which means our equation so far is            y=mx-6 and so we just need the slope

To find the slope I will use the slope formula

To use the slope formula you will need two points on the graph. I am going to pick the y intercept and the point next to it

Which means our two points are

(0,-6) and (1,-7)

The slope formula is as follows

(y₂-y₁)/(x₂-x₁)

Plug in our values and get

(-7-(-6)/(1-0)

-1/1

-1 is our slope

which means our final equation is

-x-6

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
