What is -3/4 + 3/8? Thanks.

AURORKA [14]

Answer:

$- \frac{3}{8}$

Step-by-step explanation:

First, we change both denominators to the LCM (lowest common multiple) which is 8.

$- \frac{3}{4} + \frac{3}{8} = - \frac{6}{8} + \frac{3}{8}$

Since the denominators are the same, we can add the numerators.

$\frac{ - 6 + 3}{8}$

$\frac{ - 3}{8}$

or it can be written as

$- \frac{3}{8}$

(x + 12)2 + (y+13)2 = 36 <br><br> What’s the steps to get the center and the radius?

Anon25 [30]

Step-by-step explanation:

${(x + 12)}^{2} + {(y + 13)}^{2} = 36 \\ {(x + 12)}^{2} + {(y + 13)}^{2} = {6}^{2} \\ equating \: it \: with \: \\ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ - h = 12 \implies \: h = - 12 \\ - k= 13 \implies \: k = - 13 \\ \therefore \: center \: = (h, \: \: k) = ( - 12, \: \: - 13) \\ \: \: \: \: {r}^{2} = {6}^{2} \implies \: radius \: (r)= 6 \: units$
