Answer:
A ≈ 43.3 cm²
Step-by-step explanation:
the area (A) of an equilateral triangle is calculated as
A = 
( s is a side of the triangle )
given perimeter = 30 cm , then
s = 30 cm ÷ 3 = 10 cm
then
A = 
= 
= 25
≈ 43.3 cm² ( to the nearest tenth )
Answer:
5
Step-by-step explanation:
Distance from B to B' is equal to the distance from A to A', AA'=5 so BB'=5
Answer:
24/ 23
Step-by-step explanation:
To find the slope of a line passing through 2 points
m = (y2-y1)/(x2-x1)
= (11 - -13) /( 19 - -4)
= (11+13)/(19+4)
= 24/ 23
Answer:
Less than 5
Step-by-step explanation:
The eason behind the answer being less than 5 is because if you multiply something by a fraction that is less than a whole number, then you will get less than the original number you multiplied the fraction with.
Hope this helps :)
