Answer:
D
Step-by-step explanation:
All we need to do is divide the values we are given.
12.21 / 1.48 = 8.25
Best of Luck!
Alright here it is:
-2/7x + y = -7
X = 4y
3x - y = 70
substitute the x in the second equation with the other half of the first equation.
3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11
now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating
done
Perimeter= length+length+width+width
Area=length×width
And then substitute..
Answer:
