The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation 9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +-
Answer:
The answer is 296
Step-by-step explanation:
I don't have to do a step by step equation i can look at the answer and know it is right because i am in pre-calculus
For this case, the first thing we must do is define variables.

</span>Answer:
An equation for W in terms if T is:
w (t) = (1/4) t + 11.25
Answer:
The table is not a straight line.
Step-by-step explanation:
it is curved
Answer:
Step-by-step explanation:
By definition, an Isosceles triangle has two equal sides and its opposite angles are congruent.
Observe the figure attached, where the isosceles triangle is divided into two equal right triangles.
So, in this case you need to use the following Trigonometric Identity:
In this case, you can identify that:
Substituting values, and solving for "x", you get:
Therefore, the length of BC rounded to nearest tenth, is:
