Answer:
1.6
Explanation:
first we want to figure out the square roots. the square root of 12 would be 3.5. while the square root of 3 is 1.7
after figuring out the square roots, our equation is -3.5 + 3(1.7)
first we want to multiply 3 by 1.7
this would give us 5.1
leaving our equation as -3.5 + 5.1
our final step is to add 5.1 to -3.5
although i find it easier to just subtract 3.5 from 5.1 since 3.5 is a negative.
this would give us 1.6
