Step-by-step explanation:
Perimeter = 12 + x + 6 + 2x + 5
Perimeter = 3x + 23.
Area = ½ × b × h
Area = ½ × 12 × (x + 6)
Area = 6(x + 6)
Area = 6x + 36
Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
Step-by-step explanation:
the answer is in picture
Since you are not given the following choices, by analyzing this series, it is a geometric progression because their common ratio is constant. Proofing that
4.8/(-3.2) = -1.5, also
-7.2/(4.8) = -1.5, and also
10.8/(-7.2) = -1.5
105/7 = 15
15x4= 60
105:60
I think
