Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.
Ill get back to you on this brb
Answer:
Width = (x + 8) inches.
Step-by-step explanation:
The area of the quilt is the length times the width and if we know the area and the length we can find the width by area / length.
Area = x^2 + 18x + 80 = (x + 10)(x + 8) - now we know that the length is (x + 10) so the width must be (x + 8) inches.
Let me know if you require more explanation.
