A. -3(-1) + 7 = 4
3 + 7 = 4
11 = 4 (wrong)
B. 4x - 8 = 12
4(-1) - 8 = 12
-4 - 8 = 12
-12 = 12 (wrong)
C. -2x + 3 = 1
-2(-1) + 3 = 1
2 + 3 = 1
5 = 1 (wrong)
D. 8x + 5 = -3
8(-1) + 5 = -3
-8 + 5 = -3
-3 = -3 (correct!)
So, in conclusion, D is the correct answer.
Those two numbers can't be directly added as long as they're in
radical form. The only way to add them is to find both square roots,
and then add those.
Another twist is the fact that every number has two square roots ...
one positive and the other negative. So there are four possible sums
of (√3 + √4) .
√3 = + or - 1.732051 (rounded)
√4 = + or - 2 (exactly)
The four sums are:
(+1.73205) + (+2) = <em>3.732 </em>(rounded)
(+1.73205) + (-2) = <em>-0.268</em> (rounded)
(-1.73205) + (+2) = <em>+0.268</em> (rounded)
(-1.73205) + (-2) = <em>-3.732</em> (rounded)
Step-by-step explanation:
Simplify x in the inequality.
<u>Divide </u><u>both</u><u> -2x and 4 by -2:</u>

Answer:
The sign has switched since the terms have been divided by a negative number.
The answer is 810 the digit would be 9 then you multiply by 90 it is 810
I hoped this helped!
Answer:
x = 15
