Answer:
141.12 cm^2
Step-by-step explanation:
A = 1/2 (b1+b2)h where b1 = 10.2, b2 = 12.2 and h = 12.6
so
A = 1/2(10.2 + 12.2) * (12.6)
A = 1/2(22.4)(12.6)
A = 141.12 cm^2
Answer:
sin 61 degrees = x/55
55 * sin 61 degrees = x
x is approximately 48.1 if I did the math right

Step-by-step explanation:
:)
a f(a) is the function f(x) where x is replaced by a.
So we have
(3x^2 + x + 3 - (3a^2 + a + 3)) / ( x - a)
= (3x^2 - 3a^2 + x - a) / (x = a) Answer
b (3(x + h)^2 + x + h + 3 - (3x^2 + x + 3)) / h
= (3x^2 + 6xh + 3h^2 + x + h - 3x^2 - x - 3) ) / h
= (6xh + h + 3 h^2) / h
= 6x + 3h + 1 Answer
