Step-by-step explanation:

Side length of heptagon = 20.3cm / 7 = 2.9cm.

The heptagon is made out of 7 congruent triangles, each with height 3.0cm and base 2.9cm

Hence area of heptagon

= 7 * [(0.5)(3.0cm)(2.9cm)]

= 7 * 4.35cm²

= 30.45cm².

Solve this into y=mx+b form. I don’t know how to solve this one. Please help me with the steps.
Airida [17]

Hi there!

Here are all the steps into solving this equation into the y-intercept form:

y <u>- 6</u> = 1/2(x - 2)

Add 6 on each side of the equation

y = <u>1/2(x - 2)</u> + 6

Multiply the whole parentheses by 1/2

<u>1/2 × x</u> = 1/2X

<u>1/2 × -2</u> = -1

y = 1/2x <u>- 1 + 6</u>

Add the similar terms together

y = 1/2x + 5 → ANSWER


There you go! I really hope this helped, if there's anything just let me know! :)
