Answer:

6/12

Step-by-step explanation:

Note the shaded amount of "parts". You are supposed to put the shaded amount of parts over the <em>total</em> amount of parts.

In the first rectangle, it shows 2 of 3 parts as shaded, and so the fraction is: 2/3

In the second rectangle, it shows 3 of 4 parts shaded, and so the fraction is: 3/4

Finally, the 3rd rectangle shows 6 of 12 parts shaded, and so the fraction is:

6/12

Check by multiplying the fractions across:

(2/3) x (3/4) = (2 x 3)/(3 x 4) = 6/12

6/12 is your answer.

If you need to simplify, divide common factors from both the numerator and denominator, in this case being 6.

(6/12)/(6/6) = 1/2

1/2 is your reduced answer.

What is the standard form of (6x^2-8x-7)+(8x^2-76x)
Studentka2010 [4]

Answer:  14x^2 - 84x - 7

====================================================

Explanation:

The like terms 6x^2 and 8x^2 combine to 14x^2

The like terms -8x and -76x combine to -84x

Nothing pairs with the -7, so its stays as is.

Standard form is where we list the terms in decreasing exponent order. We can think of -84x as -84x^1 and the -7 as -7x^0. So 14x^2 - 84x - 7 would be the same as 14x^2 - 84x^1 - 7x^0. The exponents count down: 2,1,0.

The final answer is a trinomial since it has three terms. It is also a quadratic because the degree (highest exponent) is 2.

5/8 + 3/4 -2/3 - 5\6​
Iteru [2.4K]

Answer:

5/8+3/4-2/3-5/6

= ( 5/8 + 3/4 ) - ( 2/3 + 3/4)

= ( 11/8) - (17 /12)

= 11/8 - 17/12

= 33-34 /24

= -1/24 (ans)
