Answer:
24×18 432 ft (hope this helps)
Step-by-step explanation:
We know that we have the formula that F = ma
Given
Force (F) = 7.5 N
Acceleration (a) = 15 m/s²
Mass (m) = ?
Now
F = ma
7.5 = m * 15
m = 7.5/ 15
Mass = 0.5 kg
60 in^2 because bxh=a and 15x4=60
Answer:
congruency means that the size and shape must be exactly the same in the figures that are compared. A triangle cannot be congruent to a quadrilateral because it has three sides whereas a quadrilateral has four. An isosceles triangle cannot be congruent to a non isosceles triangle because the sides would be different lengths.
