Answer:
D. y = 12.74(0.7)×
Step-by-step explanation:
I calculated it logically
Answer:
That is 7.
Step-by-step explanation:
112 = 2*2*2*2*7
So the smallest number is 7.
2*2*2*2*7*7 is a square number.
Answer:
242
Step-by-step explanation:
sorry this is like kinda late, but there ya go
The answer is 1:5
If you simplify both sides as much as possible by find the common factor, you get your ratio.
The common factor is 36
Divide both sides by 36
36/36 = 1
180/36 = 5
Therefore
Your ratio is 1:5
The answer
to do the calculus, the method is
taking off the paranthesis
adding the term with a similar degree
summing constant terms
(3x^2+3x+5) + (7x^2-9x+8) =
= 3x^2+3x+5 + 7x^2-9x+8
= 3x^2 + 7x^2 + 3x+5 - 9x+8
= 10x² + 3x - 9x +5 +8
= 10x² - 6x + 13
the answer is
(3x^2+3x+5) + (7x^2-9x+8) =10x² - 6x + 13
the error that Lucia did make 3x - 9x = -12x, instead of 3x - 9x = -6x
