Answer:
17
Step-by-step explanation:
4 x 2 +2= 10
12- 10=2+3 x 5
2+15
17
Use identity -
(a+b)² = a²+b²+2ab
(5+√3)² = 5²+(√3)² + 2(5)(√3)
= 25 + 3 + 10√3
= 28 + 10√3
= 2(14+ 5√3)
So when you opened up the parenthesis on the right side of the question, you added -2 to 5 instead of multiplying. Since there is no addition sign in between -2 and the parenthesis, it should be multiplication, so -2x + -10.
So now the answer would be 10 = -10.
Which leads me to believe that this question wasn't written correctly because 10 does not equal -10 for sure.
Answer:
1.57
Step-by-step explanation:
9/2 miles is the same thing as saying 9 and a half so all you need to do is 15/ 9.5 = so that is 1. 57
sum is the answer to addition problem.
less than is subtraction and "times" is multiplication.
So we have
3x+2=5x-4
So the answer is C.
Also, i'm bored so imma solve it.
3x+2=5x-4
-2 -2
3x=5x-6
-5x -5x
-2x=-6
/-2 /-2
x=3

hope it helps
