Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
Step-by-step explanation:
The equation 
can be solved by squaring both sides:
We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:
The square root of 49 equals 7, but the square root of -1 is an imaginary number.
The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
Since the scale of 2 cm to 3m is the scale that Janice is using, yes the ratio would be 2:3 so William is correct
The comlement of an angle is what you add to it to get 90 degrees
x+y=90
x is the complelemt of y and y is the complement of x
so
26+complement=90
minus 26 both sides
complement=64
the complementn is 64°
Answer:
45.6 cm
Step-by-step explanation:
Let X be the hypotenuse.
(36)^2 + (28)^2 = X^2
X = 45.6 cm
6,600,000,000 in scientific notation is 6.6 × 10^9
