2 is correct, because:
1) we have a close interval
2)we must have node on x=-5
R = 3S
R + 6 = 2 (S+6)
Substitute the first equation in the second one:
(3S) + 6 = 2 (S + 6)
3S + 6 = 2S + 12
S + 6 = 12
<u>R = 18
</u>S = 6<u>
</u>
Check:
R is 3 times S now.
In 6 years, R will be (18 + 6) = 24, S will be (6 + 6) = 12.
24 = 2 x 12 yay
The absolute value of any number will always be a positive number. That is the definition of an absolute value. It is usually denoted by the || bar. For example, when you want to find the sum of 1 and ⁻5, you write it as |1 + ⁻5|. Even though the actual answer is ⁻4, because it is in absolute value, you'll report it as +4 instead.
Answer:
B. 66 square inches
Step-by-step explanation:
Area of a trapezoid = (a + b)/ 2 * h
Where,
a = base a = 14 inches
b = base b = 8 inches
h = height = 6 inches
Area of a trapezoid = (a + b)/ 2 * h
= (14 + 8) / 2 * 6
= 22/2 * 6
= 11 * 6
= 66 inches ²
Area of a trapezoid = 66 inches ²
The correct answer is
B. 66 square inches
