Round 235,674 to the nearest thousand.<br> A. 236,000<br> B. 235,700<br> C. 235,670<br> D. 240,000
Misha Larkins [42]
To round 235, 674 to the nearest thousand...
235,674
With the number that's bold,(6) use that and the number 5( next to it.)  Since 6 is greater than the numbers 1 through 4, the 6 will move the number 5 up to 6.
So the answer is A. 236,000 to the nearest thousands.

Solve x2 + 10x + 7 = 0 by completing the square.<br><br> Which equation is used in the process?
BaLLatris [955]
x^2+10x+7=0\ \ \ \ |subtract\ 7\ from\ both\ sides\\\\x^2+2x\cdot5=-7\ \ \ |add\ 5^2\ to\ both\ sides\\\\x^2+2x\cdot5+5^2=-7+5^2\ \ \ |use\ a^2+2ab+b^2=(a+b)^2\\\\(x+5)^2=-7+25\\\\(x+5)^2=18\iff x+5=\pm\sqrt{18}\\\\x+5=-\sqrt{18}\ or\ x-5=\sqrt{18}\\\\x+5=-\sqrt{9\cdot2}\ or\ x-5=\sqrt{9\cdot2}\\\\x+5=-\sqrt9\cdot\sqrt2\ or\ x-5=\sqrt9\cdot\sqrt2\\\\x+5=-3\sqrt2\ or\ x-5=3\sqrt2\ \ \ |subtract\ 5\ from\ both\ sides\\\\\boxed{x=-5-3\sqrt2\ or\ x=-5+3\sqrt2}

Answer:

1. 4

2. -4

Step-by-step explanation:

You plug in the number given in the parentheses into the function(s) as x

for #1:

since its f(4)

you would do the following -> f(4) = 2(4) - 4 hence the answer of 4.

for #2:

since its g(2)

you would do the following -> g(2) = 2^2 - 4(2) hence the answer of -4
