Answer:
6x^2 -29 +35.
Step-by-step explanation:
use the FOIL method(First, Outer,Inner, and Last.)
2x x 3x=6x^2.
2x x -7=-14x.
-5 x 3x =-15x.
-5 x -7=35.
= 6x^2 -14x -15x+35
6x^2 -29x +35.
Answer:
x = 3
Step-by-step explanation:
2x+6=x+9 subtract x in both sides
x +6 =9 subtract 6 in both sides
x = 3
Step-by-step explanation: graph both equations where they intersect is the answer write it like this (x,y) the x and the y should be replaced with the numbers you'll get when they intersect. So if they intersected the point where they did if the y is 1 and x is 2 then the answer is (2,1). If they don't intersect at all and are parallel then it is no solution. If your only graphing one line which you aren't in this case but if you were it would be infinitely many.
3.15 addd all of them! Then divide
Answer:
625
Step-by-step explanation:
1. parenthesis first, so it simplifies to ((6+(8)2÷4*1)/2)^4
2. pemdas says that multiplication and division go before addition and subtraction, so ((6+(8)2÷4*1)/2)^4 becomes ((6+16÷4*1)/2)^4 ---> ((6+4)/2)^4
3. then simplify inside of the parenthesis, so it becomes 5^4, which is 625
