Answer:
17 units
Step-by-step explanation:
Because the triangle is isosceles, 2 of its sides are congruent; namely, the two sides that are opposite of the 2 congruent angles are contruent.
Because of the reason stated above, we can see that AC is congruent to BC, meaning that:
x+9=2x-8
-x -x
9=x-8
+8 +8
17 = x
Notice that BC is equal to x, so 17 is our final answer.
Answer:
A
Step-by-step explanation:
We take a look at this expression: 
and notice that both terms are square numbers. 
and 
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares 
, it can always be factored into 
.
Here, we can apply that. In this case, a = 7x and b = 3. So:
Thus, the answer is A.
Hope this helps!
(6•x) + 7 = 8
6x + 7 = 8
6x = 1
X = 1
Answer:
C. G(x) = (x+3)^3
Step-by-step explanation:
Inside the parenthesis, adding or subtracting numbers moves the shape along the x-axis. BUT signs have opposite effects. Adding a number moves the shape towards the negative side. Subtracting a number moves it to the positive side.
9/12 dividing both the numerator and the denominator by 3
9/3=3
12/3=4
this reduces down to 3/4
