Answer:
f(x) = 0 on x= -1 and x = -2
Step-by-step explanation:
Given function is:
In order to find the value of x on which the function will have value zero we have to factorize the function and find zeroes of the function. The method used will be factorization of polynomial as the function is in polynomial form.
So,
To find the zeroes, putting the function = 0
Hence,
f(x) = 0 on x= -1 and x = -2
Answer:
Step-by-step explanation:
Perimeter is equal to twice the length plus twice the width
Perimeter = 2L + 2W factoring out the 2
Perimeter = 2(L + W) L = (8x + 5 - 3x) W = (4x - 1)
first I would simplify L collecting the terms of x
L = (5x + 5)
plug in to L and W
Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 )) L = (8x + 5 - 3x) W = (4x - 1)
Perimeter = 2 ( 5x + 4x + 5 -1 ) collect like terms
Perimeter = 2 ( 9x +4) 2 times the 9 and 4
Perimeter = 18x + 8 SOLVE for x
Perimeter - 8 = 18x + 8 -8
Perimeter - 8 = 18x
(Perimeter - 8) / 18 = 18x / 18
(Perimeter - 8) / 18 = x
remember the Perimeter equals 88
(88 - 8) / 18 = x units
4.444444444 units = x
This seems like an odd number so let's it
Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 ))
Perimeter = 2 (( 5(4.444) + 5 ) + ( 4(4.444) - 1 )) = 87.9952
close enough with the rounding off error
=
In order to find GCF, you will need more than just 1 number
Answer:
36
Step-by-step explanation:
a² + b² = c²
a² + 77² = 85²
a² + 5929 = 7225
a² = 1296
a = 36
50 /50 I think it is the answer. i think there will be 50 non fiction and 50 fiction books in the library
