Answer:
f(2) = -2
Step-by-step explanation:
To solve this, you have to plug in 2 for x
f(2) = -2^2 + 2(2) - 10
= 4 + 4 - 10
= 8 - 10
= -2
Given:
S1 = 6 m
S2 = 8 m
S3 = 10 m
h = 3 m
Lateral Area Formula :
LA = hP ; height * perimeter
= 3m * (6 + 8 + 10)
= 3m * 24
LA = 72 m²
Surface Area Formula:
SA = 2B + hP : B = area of the base = ab / 2 = (6m * 8m)/2 = 48/2 = 24m²
SA = 2(24m²) + 72m²
SA = 48 m² + 72 m²
SA = 120 m²

Step-by-step explanation:
Answer:
x = 37 / 7
Step-by-step explanation:
the angles shown here are pair of alternate interior angles .
which are equal,
so,
=》12x - 18 = 5x + 19
=》12x - 5x = 19 + 18
=》7x = 37
=》x = 37 / 7
