Answer:
-1(x-2)(x-3)
Step-by-step explanation:
first we factor the negative:
-1 (x^2 - 5x +6 )
the next step, (if possible) is to guess 2 numbers that multiplied are 6
and added are -5
in this case is easy to see that those numbers are -2 and -3
The solution then is:
-1(x-2)(x-3)
If guessing the 2 numbers doesn't work, you need to complete the square
It is 45 yd from the base of the pole.
The pieces of the right triangle we are given are one of the legs (the height of the pole, 60 yd) and the hypotenuse (the length of the cable, 75 yd). Using the Pythagorean theorem, we have:
60²+b²=75²
3600+b²=5625
Subtract 3600 from both sides:
3600+b²-3600=5625-3600
b²=2025
Take the square root of both sides:
√(b²) = √2025
b = 45
Answer:
-36x5=69
Step-by-step explanation:
Because 69 is superior
A medical researcher need to select 6 people out of 13 people who have volunteered for the test in
To find, how many ways can 6 people be selected.
= 
=
To find the mean, you add up all the numbers and divide by the number of numbers in the sequence
28+42+56+70+84+98+112
=490 divide by 7
=70
