Solve the top equation for x and then substitute that into the bottom equation and solve for y:
Top equation: subtract 4 from both sides to get x = y - 4
Substitution and simplify:
y = 4(y - 4) - 10
y = 4y - 16 - 10
y = 4y - 26
-3y = -26
y = 26/3 or 8 1/3 or 8.333 (those are all the same but in different forms)
Perimeter- 14x+6
Just add al the sides up like normal
Area- 12x^2+9x
Multiply the length and width
C)
Perimeter- 118
Area- 840
I’m pretty sure these are right
I know 6% of $3000 is $180
But I don't understand the rest of the question.
Answer:
x + 8
Step-by-step explanation:
when theres just an x or any number there it is the same as 1x
2x - 1x = 1x / x
1x + 8 aka x + 8
