Answer:
x=-10, y=-20
Step-by-step explanation:
Since both 2x and 3x+10 equals y, they equal each other.
2x = 3x + 10
x = -10
Substitute -10 for x
2(-10) = y
y=-20
Step 1: plug in the numbers. 7(6)-4
Step 2 multiply 7x6 42-4
The length equals: 28 then height equals 13.2 because you do perim divide by length which gives you height, then u check and do 13.2 times 28 and get 369.6 then you just round the 6.
