Step-by-step explanation:
The x coordinate of a y intercept of a line is always zero, because the y intercept is the point at which the line cuts the y axis, which is located at the position x=0. If the y axis is located at x=0, then the y intercept will also be located at x=0.
Answer:
w = 6
Step-by-step explanation:
Givens
Area = 90
Let the width = w
Let the length = 2w + 3
Formula
Area = L * W
Solution
Area = (2w + 3)*w
Area = (2w + 3)* w = 90 Remove the brackets.
Area = 2w^2 + 3w = 90 Subtract 90 from both sides.
2w^2 + 3w - 90 = 0
This will factor into
(w - 6)(2w + 15) = 0
Only w - 6 will = a zero that makes sense when speaking of an area
w - 6 = 0
w = 6
L = 2*w + 3
L = 2*6 + 3
L = 15
The width is 6
The Newfoundland weighs 45076 more grams the Springer spaniel.
Springer Spaniel = 20450 grams Cocker Spaniel = 12870 grams Newfoundland = 65526 grams. 65526 - 20450 = 45076
