Answer:
The ratio is the same
Step-by-step explanation:
Bianca- 20:14
= 10:7
Logan- 10:7
The ratio is the same
This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
Answer:
70.86 degrees
Step-by-step explanation:
cos x = adjacent side / hypotenuse
= 2/6.1 = 0.32787
x = 70.86.
Step-by-step explanation:
X^a times X^b = X^a + b
so 4x times 6x = 24x^(1+1)
Answer:
f(x)
Step-by-step explanation:
f(x)=x-1/x+5
y=x-1/x+5
xy+5y=x-1
xy-x=-1-5y
x(y-1)=1-5y
x=-1-5y/y-1
x=-5
