= (7u³ + 8u² + 7) + (8u³ - 3u + 7)
Operate like terms together:

= 7u³ + 8u³ + 8u² - 3u + 7 + 7
= 15u³ + 8u² - 3u + 14

In short, Your Answer would be: 15u³ + 8u² - 3u + 14

Answer:

$15u^3+8u^2 -3u+14$

Step-by-step explanation:

Like terms are those terms which have same variable to the same power.

Simplify:

$(7u^3+8u^2+7)+(8u^3 -3u+7)$

Remove the bracket:

$7u^3+8u^2+7+8u^3 -3u+7$

Combine like terms;

$15u^3+8u^2 -3u+14$

Therefore, the sum of $(7u^3+8u^2+7)+(8u^3 -3u+7)$ is, $15u^3+8u^2 -3u+14$

Answer:

(Véase la explicación para mayores detalles/See the explanation for further details)

Step-by-step explanation:

a) Tres al cubo (Three to cube):

$x = 3 \times 3 \times 3$

$x = 3^{3}$

$x = 27$

b) Seis al cubo (Six to cube):

$x = 6 \times 6 \times 6$

$x = 6^{3}$

$x = 216$

c) Cinco al cuadrado (Five squared):

$x = 5 \times 5$

$x = 5^{2}$

$x = 25$

d) Ocho al cuadrado (Eight squared):

$x = 8 \times 8$

$x = 8^{2}$

$x = 64$

e) Dos a la quinta (Two to five):

$x = 2 \times 2 \times 2 \times 2 \times 2$

$x = 2^{5}$

$x = 32$

f) Diez a la cuarta (Ten to four):

$x = 10\times 10 \times 10 \times 10$

$x = 10^{4}$

$x = 10000$

Paige used 1 1/2 cups of flour and 1/4 cup of butter to make 12 muffins. How much flour and butter would palat

yanalaym [24]

Answer:

Step-by-step explanation:

To turn the fraction of 1 1/2 to decimal would be : 1.50 add fifty percent because you have to add 6 to 12 and six is half, so you add half. Half of 150 is 75 so add them you get 225 and as a fraction, that's 2 1/4. Already you have the first part done. Since there is only one answer with 2 1/3 your answer has to be D.
