What is the value of x to the nearest tenth? x = __ (if you could explain how i can calculate this that'd be great because i don't get it at all; but it's alright if you don't)

14.4

The mnemonic SOH CAH TOA can help you remember that ...

... Tan = Opposite/Adjacent

In this figure, you have a right triangle with an angle, its adjacent side, and its opposite side marked. The above relation tells you ...

... tan(64°) = x/7

Multiplying by 7 gives the value of x.

... 7·tan(64°) = x ≈ 14.3521 ≈ 14.4

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
