Answer:
(7x+4) and (4x)
Step-by-step explanation:
The expression are (7x+4) and (4x)
Well, whenever a number is next to a variable or next to parenthesis, (a variable is the letter[s] used to represent a value in the problem, such as 3b in this question), that means you would multiply the number times the letter, or the number times the answer in the parenthesis. So since we know a = 9, and b = 2, let's solve the equation now! :D
Now according to the order of operations of PEMDAS, let's solve what's in parenthesis first.
5(a + 3b)
⇒ a + 3b
⇒ a (a = 9), + 3 times b (b = 2)
⇒ 9 + 3 × 2
⇒ 9 + 6
⇒ 15.
⇒ 5(15)
⇒ 5 × 15
⇒ 75.
After doing all steps with the help of the order of operations of PEMDAS, your final answer would be 75. =)
I hope I helped! ^-^
Answer:
57 degrees! : D
Step-by-step explanation:
Every triangle angles(all of them) add up to 190 degrees.
so 33+x+90 degrees.
Why do we add 90 degrees? because there is a little "square on the bottom right explaining that it is a 90-degree angle.
so 33+90=123
so x=180(our original sum) minus 123
and so x=57 degrees
There is no picture so I can't help.
