4. x^2+13x+42
5. x^2+17x+72
6. x^2-25
7. x^2-9
8. x^2+20x+100

10. x^2+x-12
Answer:
Below
Step-by-step explanation:
The length of this triangle is 3x+1 and the width is x.
The perimeter P is:
P= 2(3x+1)+2*x
P= 6x+2+2x
P= 8x+2
Let's evaluate it when x=1/2
●1/2 =0.5
P= 8*0.5+2 =4+2= 6 ft
●●●●●●●●●●●●●●●●●●●●●●●●
The area A is:
A = (3x+1)*x
A= 3x^2 +x
Let's evaluate it when x=0.5 feet
A= 3*0.5^2 +0.5
A= 3*0.25+0.5
A= 0.75 +0.5
A= 1.25 ft^2
Answer:
7/5 * A *y =k
Step-by-step explanation:
A=5k/7y
Multiply each side by 7y
A* 7y = 5k/7y * 7y
7Ay = 5k
Divide by 5
7Ay/5 = 5k/5
7/5 * A *y =k
