Answer:
Step-by-step explanation:
x^2 - 9x - 70
we need to find two numbers whose sum is -9 and product id -17
The numbers are -14 and 5
By splitting the middle term,
x^2 - 14x + 5x - 70
= x ( x - 14 ) + 5 ( x - 14 )
( x + 5 ) ( x - 14 )
Hope this helps
Plz mark as brainliest!!!!!
I tried working it out but I am not sure
The answer is 99/20 or 4.95 or 4 19/20
The Power of a Product property tells us that when you multiply two numbers with the same base, you can add their exponents to determine the product.
For example,

*

=

.
The Power of a Quotient Property tells us that when you divide two numbers with the same base, you can subtract their exponents to determine the quotient.
For example,

/

=
Answer:
D
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, hence
(BC)² = 10² + 30² → D
