Answer:
length=11 width=10
Step-by-step explanation:
Create two equations with length(l) and breath(w) as our unknowns
2l+2w=42
2l=42-2w
2l/2=(42-2w)/2
l=21-w(equation 1)
lxw=110
lw=110
Substitute equation one into equation two
(21-w)w=110
21w-w²=110
Write your equations in standard quadratic form
0=w²-21w+110
solve this as a quadriatic tri nominal
0=(w-10)(w-11)
0=w-10. or 0=w-11
10=W. 11=L
Answer:
1) you can make 32 bows
2) a. 16 b.8
Step-by-step explanation:
1) if you have 16 meters of ribbon and it takes 1/2 meters to make one now, you would divide 16 by 1/2 and get 32
2)if you divide 8 by 0.5 you get 16 and if you divide 4 by 0.5 you get 8
Answer:
Step-by-step explanation:
Perform the indicated multiplication first:
25000 - 500bx + 50ax - abx²
It would seem that this should be part of an equation, and that the other part is missing; without another part, there's no way to determine the values of a and b. Please ensure you have copied this problem down completely.
D the slope for function A one is -2 and the slope for function B is 4
