Step-by-step explanation:
M equals 3.5
Answer:
Step-by-step explanation:
b(a + 1) + a = b*a + b + a = ab + b + a
1) b(2a +1 ) = b*2a + b*1 = 2ab + b Not equivalent.
2)a + (a +1)*b = a + ab+ b Equivalent
3) (a +1)(b+ a) = a*(b +a) + 1*(b+a) = ab+ a² +b + a Not equivalent.
4) (a + 1)b + a = ab+ b + a Equivalent
5) a + b(a+1) = a +ab + b Equivalent
6) a + (a +1) + b = a + a + 1 + b = 2a + 1 +b Not equivalent.
7) a(b +1) + b = ab + a + b Equivalent
Simple....
you have:

to convert them into
improper fractions:
1.) Take whole number*denominator
(5*5=25)
2.) Take what you got...and
add the numerator
(25+2=27)
3.) Use the original denominator

Do the same to the other one...
2*13=26
26+10=36

Now..add...

But..you need a common denominator!


Now you can add!

When simplified....

Thus, your answer.
Answer:
x = 23
Step-by-step explanation:
This entire angle makes up 90° b/c of the square box
65 + x + 2 = 90
x + 67 = 90
x = 23
