Answer:
49 - x^2
Step-by-step explanation:
(7+x)(7-x)
We know this is the difference of squares
(a-b) (a+b) = a^2 - b^2
7^2 - x^2 = 49-x^2
We can also FOIL
first = 7*7 = 49
Outer: = 7x
Inner: = -7x
Last : -x*x = -x^2
Add them together
49 +7x-7x - x^2
Combine like terms
49-x^2
Answer:
P(candy chosen is red) = 58/200
Step-by-step explanation:
Answer:9
Step-by-step explanation:when an absolute value has a negative it turns to a positive which makes this problem 3x3
So, we are looking for F of G of 2. So, we need to work backwards and find G(x) first.

So we know that g(-2) = -6, now we take thatt -6 and plug in into f(x)

68 is the answer
Answer:
The answer is b = 6
Step-by-step explanation:
Area of a triangle= 1/2 × b × h
A = 21, h = 7, b = ?
21 = 1/2 × b × 7 (multiplying through)
21 = 7b/2
Cross multiply
2 × 21 = 7b
42 = 7b
b = 42/7
b = 6
