Answer:
Step-by-step explanation:
At = 2*(h×w + h×l + w×l)
= 2*(4.8×3.1 + 4.8×7.2 + 3.1×7.2)
= 2*(14.88 + 34.56 + 22.32)
= 2*71.76
= 143.52 cm²

Answer:
y= 7
Step-by-step explanation:
Plug in values into y=mx+b
m= slope
b= y intercept
Since slope is 0, y will always be at 7.
y= 0(x) +7
y= 7
Answer:
x=22.5
Step-by-step explanation:
Make a ratio
The names of the triangle help with this.
AB is similar to FG, and AC is similar to FH (the missing side)
6/15 = 9/x
cross multiply
6x=135
divide both sides by 6
x=22.5
The number u looking for is 28
