Answer:
<h2>135 ft²</h2><h2 />
Step-by-step explanation:
see attached image
<u>shaded area = total area (1) - unshaded triangular area (2)</u>
1. area of a trapezoid = (a + b) * h/2
where a = 8, b = 18, h = 15
Area of trapezoid = (8 + 18) * 15/2 = 195 ft²
2. Area of unshaded triangle = 1/2 (8) 15 = 60 ft²
shaded area = 195 - 60 = 135 ft²
Answer:
Step-by-step explanation:
Put the appropriate values of n in the formula and do the arithmetic.
a(1) = 3·1 -7 = -4
a(5) = 3·5 -7 = 8
The 1st and 5th terms are -4 and 8.
_____
The first few terms of the sequence are ...
-4, -1, 2, 5, 8, 11, 14, ...
Answer:
60 animal balloons
Step-by-step explanation:
15 times 3 equals 45 so 20 times 3 equals 60 balloons
0= -3x+9
-9=-3x
3=x
Final answer: x=3
There is only one zero because it is linear, and can therefore only cross the x axis once.
