Hi DerpyIntelligence!
The product is addition so we do -3 1/4+-1 1/2. We solve it like this. We separate each part like this (-3)+(-1/4)+(-1)+(-1/2) then we solve the whole parts (-3)+(-1)=(-4). Next we find out the LCD of (-1/4) and (-1/2) which is 4 so we change (-1/2) to (-2/4) than we add (-1/4) which is (-3/4). Finally we add the wholes to the fractions (-4)+(-3/4)=(-4 3/4)
Hope this helps!

Answer:

Mixed number is 4\frac{7}{8} and the simplified form of this mixed number is \frac{39}{8}.

Step-by-step explanation:

The two mixed numbers are

-3\frac{1}{4}=-\frac{13}{4}

and -1\frac{1}{2}

= -\frac{3}{2}

Now we will multiply these negative fractions.

(-\frac{13}{4})(-\frac{3}{2})

When two negative signs get multiplied they become positive.

= \frac{13}{4}\times \frac{3}{2}

= \frac{39}{8}

= 4\frac{7}{8}

Therefore, mixed number is 4\frac{7}{8} and the simplified form of this mixed number is \frac{39}{8}.

Which of the following are solutions to the following equation?
Alecsey [184]

Answer:

x=-7

x=7

Step-by-step explanation:

we have

2x^{2}-98=0

Solve for x

Adds 98 both sides

2x^{2}-98+98=0+98

2x^{2}=98

Divide by 2 both sides

2x^{2}/2=98/2

x^{2}=49

take square root both sides

x=\pm7

therefore

The solutions are

x=-7

x=7

How is a trapezoid similar to a parallelogram
Svetllana [295]
Trapezoid and paralellogram are both quadrilaterals

the heiarchy is
quadrilaterals are 4 sided figures
quadrilaterals is split up into
      A. no pairs of paralell sides
             - kite
       B. 1 pair of paralell sides
               - trapezoid/trapezium
      C. 2 pairs of parell sides (paralellograms)
           -rectangles
           -rhombus
           -square


so you can see that they are both quadrilaterals (quad=4, lateral=sides, quadrilateral=4 sided figure)

Answer:

If angle dgf as an angle of 108

that means that the equation would look like this x + 4x-2=108

= 5x-2=108

then you solve for x

5x=110

110/5 = 22 = x

hope that answers your question
