In triangle b. we know that tan(x) = Opposite side to x angle / Adjacent side to angle x.
By substituting in above formula,
tan(x) = 12/5 = 2.4
x = tan^-1(2.4) = 68 degrees.
And in triangle a. i am not clear with the angle. Is it 51 or any other?

Please answer the question from the attachment.

Change it into improper fraction to make it easier or just solve it as is.
=3\frac{5}{8}-2\frac{7}{8}
=\frac{29}{8}-\frac{23}{8}
=\frac{6}{8}=\frac{3}{4}            
OR
=3 \frac{5}{8}-2 \frac{7}{8}
divide it to two parts:
3-2=1 and \frac{5}{8}-\frac{7}{8}=\frac{-2}{8}
1\frac{-2}{8}⇒(1×8-2=6)
=\frac{6}{8}=\frac{3}{4}

Rewrite the expression using distributive property : 30x + 6
Anit [1.1K]

Answer:

This cannot be done, but it can be factored as: 6(5x + 1)

Step-by-step explanation:

This expression cannot be distributed any further.

The distributive property is used when multiplying polynomials (multiplying one or more terms by two or more terms). In which case, each term in multiplied by each of the terms in the bracket, for example: .

5(x + 2)  =  5x + 10

We can factor this expression however to go the opposite direction:

30x + 6

Since 30 and 6 are both divisible by 6, we can factor it out of each term.

Divide 30x by 6 and divide 6 by 6.

6(5x + 1)
