Answer:
x = -2 or x=-5
Step-by-step explanation:
sqrt(x+6)-4 = x
sqrt(x+6) = x+4
square both sides
x+6 = x²+8x+16
x²+7x+10 = 0
(x+2)(x+5) = 0
x = -2 or x=-5
Substitute in original equation
x=-2 +/- sqrt(-2+6)-4 = 2-4 = -2 checks
x=-5 +/- sqrt(-5+6)-4 = -1-4 = -5 checks
Answer:
2000
Step-by-step explanation:
One way to do this is to add half of a thousand, then zero all digits to the right of the thousands place.
2371 +500 = 2871
With digits zeroed, this is ...
2000

<em>Additional comment</em>
The traditional instruction is to look at the digit in the place to the right of the thousands place. (It is 3.) If it is 5 or more, you increase the number by 1 in the place you're rounding to. (No increase is needed.) Then you set all digits to the right of the thousands place to zero.
2371 rounds to 2000
The price is 325 - 215.75 = 109.25 $ lower.

Well first of all, if one angle is 95 degrees, then both other angles MUST be acute.
An infinite number of triangles can be made, just as long as the other two angles add up to 85 degrees.
2 is the tens position meaning 2 tens
