Answer:
It’s definitely 1/4
Step-by-step explanation:
the answer shoudl be positive since its a positive line
And t can’t be 4 becuase then the line would be slanted upward as becuase 4 up 1 right and this looks more like of a 1 up, 4 right. Try it yourself, try slope fo 4 from the origin since its a gaurteed point in this situation and try 4 and 1/4. 1/4 is way more reasoabnable,
40:1,2,4,5,8,10,20,40
60:1,2,3,4,5,6,10,12,15,20,30,60
The GCF between 40 and 60 is 20
Step-by-step explanation:
use the identity a²-b²=(a-b)(a+b)
x²-4=(x-2)(x+2)
so the answer is x-2
a 
7
because 4a + 7 - 7 35 - 7
equals 4a 28
and 4a/4 28/4
equals a 7
Answer:
L = 16
w = 10
Step-by-step explanation:
Givens
Area = 160 sqr inches
width = x
length = x + 6
Equation
Area = L * w
Solution
Substitute in the equation all of the givens.
160 = x(x + 6) Remove the brackets
160 = x^2 + 6x Subtract 160 from both sides.
160-160 = x^2 + 6x - 160
0 = x^2 + 6x - 160
This equation factors. Turn it around first
x^2 + 6x - 160 = 0
(x - 10)(x + 16) = 0
Answer
x (width) = 10
x + 16 = 16
