Let S(n) the statement, 2 is a factor of .
For n=1, 1^2 + 7(1) = 1 + 7 = 8, 1 is a factor of 8, then S(1) is true.
For n=2, we have 2^2 +7(2) = 4 +14 = 18, of course, 2 is a factor of 18, then S(2) is true.
For n=3, we have 3^2 +7(3) = 9 +21 = 30, of course, 2 is a factor of 30, then S(3) is true.
Given:
Number calories in a 6-inch pizza = 640 calories
For the pizza of 6 inch
For the pizza of 12 inch
Number calories in a 6-inch pizza = 640 calories, therefore:
Substitute:
And solve for x:
Now, Estimate the number of calories in one slice of a 12 inch pizza:
Answer: 320 calories
Answer:
4*sqrt(2)
Step-by-step explanation:
lets use Pythagorean Theorem
a^2+b^2=c^2
4^2+4^2=c^2
16+16=c^2
32=c^2
|c|=sqrt(32)
|c|=sqrt(4*4*2)
|c|=4*sqrt(2)
c= ±4*sqrt(2)
since distance can't be negative, the answer is +4*sqrt(2) or just 4*sqrt(2)
34=x
180-68 =112 so angle PQS is 112 4x-3x is x so PSQ is x and now you can do x +x + 112 = 180 2x-68 x=34
I probably got it wrong tho, so sorry if it is incorrect
