Simplify:
2(4p – 3) + (p + 7)
a. 5p + 1
b. 5p + 4
c. 9p + 1
d. 9p + 13

C. 9p + 1

Step-by-step explanation:

2(4p - 3) + (p + 7)

Step 1:  Distribute 2 in the first term to both terms in the parenthesis.  You can drop the parenthesis on the second term (p + 7)...

2(4p) + 2(-3)  + p + 7      

Now multiply

8p - 6 + p + 7

Now simplify by combining like terms

8p + p -6 + 7

   9p + 1            (8p + p = 9p, -6 + 7 = 1)  

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
