Answer:
-52
Step-by-step explanation:
Let’s find x and y
x=7 and y=3
so 7x2=14
3x22=66
14-66=-52
Answer:
The numbers are 16 and 20
Step-by-step explanation:
Let the multiples be: x+4 and x+8
Sum is 36, so we can make an equation:
x+4+x+8=36
2x=36-12
x=12
The numbers are 12+4=16, 12+8=20.

Answer:u need to x out some of them tabs
Answer: 102cm²
Step-by-step explanation:
Area of base = 6 × 7 ÷ 2 = 21
Area of lateral face = 6 × 9 ÷ 2 = 27
Since all of the sides of the base are equal, we can multiply the area of 1 lateral face by 3 to get the area of all the lateral faces.
27 × 3 = 81.
Now we add up the area of the base and the lateral faces.
21 + 81 = 102cm²
