Answer:

No real solutions.

B is correct

Step-by-step explanation:

Given: 3x^2+x+10=0

We are given a quadratic equation and need to solve for x.

Quadratic formula: ax^2+bx+c=0

x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

For our equation, a=3, b=1 and c=10

Substitute the value of a, b and c into formula

x=\dfrac{-1\pm\sqrt{1^2-4\cdot 3\cdot 10}}{2\cdot 3}

x=\dfrac{-1\pm\sqrt{-119}}{6}

Here, Roots are imaginary because number inside the square root is negative.

Hence, No real solutions.

Answer:

A) SAS

Step-by-step explanation:

The picture gives us that two sides are congruent. We can see that an <em>angle</em> is congruent as well because they share a common point at their tip.

If we look at just the area of intersection, it looks like an X. Think of the X as two lines intersecting. Each side equals 180°, and because both triangles are made up of those sides, we can conclude that the angles are congruent as well.

Hope this helps!

3q - 16q = 7 + 2(-89 – 3)
levacccp [35]

Answer:

q = 177/13

Step-by-step explanation:

3q - 16q = 7 + 2(-89 – 3)

-13q = 7 + 2(-92)

-13q = 7 - 184

-13q = -177

q = (-177)/(-13)

q = 177/13

i have 60+8x=108 x=6 but for the other equation i dont know how to get rid of the 3x to solve for the y.
LUCKY_DIMON [66]
Angle a is congurent to angle e, so 60+8x=108
same with c and g.
so 8y-3x=62
just plug in x for there (6)
so 8y-24=62
then 8y=88
y=11

Thomas arrived at the library at 11:45 AMHe left 1 hour 40 minutes laterAt what time did Thomas leave the library?
andre [41]

Answer:

At 1:25 P.M.

Step-by-step explanation:

Thomas arrived at the library at 11:45 AM and he left 1 hour 40 minutes later.

So, 1 hour 40 minutes is equivalent to (60 + 40) = 100 minutes.

Now, after 15 minutes, the time will be 12 P.M.

So, remaining (100 - 15) = 85 minutes i.e. 1 hour and 25 minutes the time will be 1:25 P.M.

Therefore, Thomas leaves the library at 1:25 P.M. (Answer)
