Answer:
X=9 or x=-9
Step-by-step explanation:
X^2=81
Can be written as
x^2-81=0
Factorize by the property:
a^2-b^2=(a-b)(a+b)
So the expression becomes:
(x-9)(x+9)=0
Therefore, either x-9=0or x+9=0
Then the solutions are x=9 or x=-9
The answer is b so good luck and i hope that helps
A.) The clerk has - 16 oranges 20 apples 24 pears
he needs to put all three fruits into baskets without any leftover fruits
each basket should have equal amounts of each fruit
so to find the largest number of baskets he can make we have to find the highest common factor for 16,20 and 24
so lets find the factors for each of these
16 - 1,2,4,8,16
20 - 1,2,4,5,10,20
24 - 1,2,3,4,6,8,12,24
from the given factors the common factors for all three are 1,2 and 4
from these the highest factor is 4
therefore the largest number of baskets he can make are 4
in each basket there will be
4 oranges 5 apples 8 pears
answer is 4 baskets
Answer:
I'd say A is the correct answer. There's a chance I'm wrong but I don't think so
Im going to assume that 3√ is √3
And √3 is irrational because You cant square root it without getting nuked with a Random Number generator of decimals.
