That is what you're asking right? I'm just going by the last one.
Answer:
Step-by-step explanation:
3/x=5/7 is the same as A 21=5x Both equal to 21/5 or 4 1/5
Answer:
a(x)=2x^2+9x+4
Step-by-step explanation:
We have been given the length and width, as well as the formula to find the area:
Length: 2x + 1
Width: x + 4
A = l * w
A = (2x + 1)(x + 4)
2x^2 + 8x + x + 4
We can add like terms now:
2x^2 + 9x + 4
Our area is 2x^2 + 9x + 4
Our answer would be a(x)=2x^2+9x+4
38 because 80% of 20 is 18 and then add the 2
