Net 2....................
Assume that the length of the rectangle is "l" and that the width is "w".
We are given that:
(1) The length is one more than twice the base. This means that:
l = 2w + 1 .......> equation I
(2) The perimeter is 92 cm. This means that:
92 = 2(l+w) ...........> equation II
Substitute with equation I in equation II to get the width as follows:
92 = 2(l+w)
92 = 2(2w+1+w)
92/2 = 3w + 1
46 = 3w + 1
3w = 46-1 = 45
w = 45/3
w = 15
Substitute with w in equation I to get the length as follows:
l = 2w + 1
l = 2(15) + 1
l = 30 + 1 = 31
Based on the above calculations:
length of base = 31 cm
width of base = 15 cm
Answer:
A
Step-by-step explanation:
The solution to f(x) = g(x) occurs where the two graphs cross. That's at the point (-2, -1).
Answer A.
X represent the number of laps Marcy swam, 1 1/4x represent the number of times Toni swam.
20 + 0.80(1 1/4x) + 15 + 0.85x = 257
20 + x + 15 + 0.85x = 257
1.85x + 35 = 257
Required equation is 1.85x + 35 = 257
Set the first integer be x, and we have the equation x+x+1+x+2=-144, x =-49, the three numbers are -49,-48,-47
