There's an identity
sec^2 x = 1 + tan^2 x
so here we have
sec^2 theta = 1 + (3/8)^2 = 73/64
sec theta = sqrt 73 / 8 or 1.068 to nearest thousandth
Answer: 8x + 6a
Step-by-step explanation: Combine your "x" terms and your "a" terms.
So 3x + 5x is 8x and 2a + 4a is 6a.
So the answer is 8x + 6a.
Answer:
Just like combining like terms with the same variables, you combine like
radicals with the same number under the radical signs.
Step-by-step explanation:
Example:
3x + 2x
= 5x {combined like terms}
3√2 + 2√2
= 5√2 {combined like radicals}
258 = 240 + 18
258: 6 = (240 + 18) : 6 = 240 : 6 + 18 : 6 = 40 + 3 = 43
Your answer is 43.
