The GCF of 7 and 14a is 7, so the factors are:-
7(1 + 2a)
Answer:
The first one
Step-by-step explanation:
Tan(35)=x/12
.7=x/12
12*.7=x
x=8.4
A - area of a trapezoid;
a, b - two bases.
A = h * ( a + b ) / 2 / * 2 ( we have to multiply both sides by 2 )
2 A = h *( a + b )
2 A = h a + h b
h b = 2 A - h a
b = ( 2 A - h a ) / h
b = 2 A/h - a
Answer: D )
