Answer:
135 units²
Step-by-step explanation:
height = √17²-8²=√289-64=√225=15
area = 9×15 = 135 units²
Answer:
68?
Step-by-step explanation:
multiples of 5 end in 5 or 0
_ _ _
last digit has 2 choices ( 5 and 0 )
1,3,5,7,9 are odd
so tens digit has 5 choices but we see that 5 is repeated so we split into more cases
when last digit is 0, tens digit has 5 choices then hundreds digit has 8 choices so 1*5*8=40
when last digit is 5, tens digit has 4 choices and hundreds digit has 7 choices (0 can't be first digit) 1*4*7=28
40+28=68
Answer: Second option.
Step-by-step explanation:
By defintion, a Quadratic function is a polynomial of degree 2 and it has the following form:

Therefore, the function given is Quadratic. This is:

The steps to find the roots (or the x-intercepts) of the function, are:
1. You must substitute
:

2. Now, you can factor the Quadratic equation. Choose two numbers whose sum is 6 and whose product is 9. Notice that:

Therefore, you will get a "Double root".
4. So the solution is:
