Answer:
A
Step-by-step explanation:
there is a constant pattern from one term to another
add -7 to get to the next term
slope = - 
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 3y = - 12 into this form
subtract 2x from both sides
3y = - 2x - 12 ( divide all terms by 3 )
y = -
x - 4 ← in slope- intercept form
with slope m = - 
1/3 = 0.333333
87/100 = 0.87
The circumference of the circle based on the equilateral triangle is 63mm.
<h3>How to calculate the circumference?</h3>
The side of the triangle is 20mm. The radius will be:
= 20/2 = 10
The circumference of the circle will be:
= 2πr
= 2 × 3.14 × 10
= 63
In conclusion, the circumference is 63mm.
