Answer:
x= -16/13 y= -41/13 I think
Step-by-step explanation:
Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
10 out of 10 equals 1.
then there is 9 left.
This gives 1 and 9 over 10.
9 over ten is not a whole number as 10 over ten is.
Hope this helps.
The answer will be -3.3. Hope this helps!
