Answer:
AREA =18
Step-by-step explanation
think of a rectangle, 12 by 3 which is also 12*3
so you do 12*3=36
but since it is a triangle you have to divide it by 2
36/2=18
18
Each tricycle has 3 wheels and one seat, so the ratio of seats to wheels is 1:3
Answer:
A) 40
Step-by-step explanation:
The sum of the interior angles of a regular polygon is:
For a hexagon, we put n=6
Let x be the 6th interior angle, then
The largest interior angle is 140°
Therefore the least exterior angle will be:
The correct choice is A
Answer:
Step-by-step explanation:
Y = mx + b
-1/2 x + 3y = -3
3y = 1/2 x -3
y = 1/6 x - 1
Where slope m = 1/ 6and y intercept b = -1
Assume that the number is n.
sum of twice the number and 15 means that you will first multiply the number by 2 then add 15.
the equation us:
2n + 15 = -42
2n = -42-15
2n = -57
n = -28.5
