Example: 2x+2y=8 and 3y+2x=6
Okay so u first want to put on of the equations into a y= form. So let's use 3y+2x=6. Subtract 2x from both sides. 3y=6-2x divide by 3. Y= 6-2/3x or y= -2/3x + 6. Now just plug this new equation in for Y since "y=" into the other equation.
2x + 2(-2/3x + 6) = 8.
Then you would distribute the 2 into the parenthesis and simplify to solve for x.
After you solve for x, plug x into one of the original equations to find y.
Answer:
B, 224in2
It may get tedious but just find the area of each face and write them down
Step-by-step explanation:
Answer:
56 ft
Step-by-step explanation:
Perimeter is the distance around the shape
18 x 2 + 10 x 2 =
36 + 20 =
56 ft
D. is the answer because it has multiplication
3x4= 12+2= 14 (the dot means multiplication) and i dont know further srry :(
