6a. 1 - 2sin(x)² - 2cos(x)² = 1 - 2(sin(x)² +cos(x)²) = 1 - 2·1 = -1
6c. tan(x) + sin(x)/cos(x) = tan(x) + tan(x) = 2tan(x)
6e. 3sin(x) + tan(x)cos(x) = 3sin(x) + (sin(x)/cos(x))cos(x) = 3sin(x) +sin(x) = 4sin(x)
6g. 1 - cos(x)²tan(x)² = 1 - cos(x)²·(sin(x)²)/cos(x)²) = 1 -sin(x)² = cos(x)²
The answer is <u>A. 98</u>.
Because when you subtract 115 - 45 it equals 70 then you add 70 + 69 which equals 139 then you subtract 237 - 139 it equals <u>98</u> which is your answer!

M/2 - 5 + 3 = 2
Put each term in m/2 - 5 + 3 over the common denominator 2: m/2 - 5 + 3 = m/2 - 10/2 + 6/2:
m/2 - 10/2 + 6/2 = 2
m/2 - 10/2 + 6/2 = (m - 10 + 6)/2:
(m - 10 + 6)/2 = 2
Subtract like terms. 6 - 10 = -4:
(m - 4)/2 = 2
Multiply both sides of (m - 4)/2 = 2 by 2:
(2 (m - 4))/2 = 2×2
(2 (m - 4))/2 = 2/2×(m - 4) = m - 4:
m - 4 = 2×2
2×2 = 4:
m - 4 = 4
Add 4 to both sides:
m + (4 - 4) = 4 + 4
4 - 4 = 0:
m = 4 + 4
4 + 4 = 8:
Answer: m = 8
