Answer:
2, 16 and 256.
Step-by-step explanation:
Just substitute for n:-
first term ( when n = 1) = 2 * 2^(1-1)
= 2 * 1 = 2
4th term = 2 * 2^(4-1) = 16
8th term = 2* 2^(8-1) = 256
It must be noted that the area of the square is calculated through the equation,
A = s²
where A is area and s is the measure of one side of the square.
To determine the measure of one side of the square, we simply have to get the square root of the area,
s = √A
Substituting the known value,
s = √75 ft² = 5√3 ft ≈ 8.66 cm
Thus, the answer to this question is approximately 8.66 cm.
Answer:
Step-by-step explanation:
we know that
The formula to find the sum is equal to
where
a1 is the first term
an is the last term
n is the number of terms
In this problem we have
substitute the values in the formula
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
