L = 59+2w
diagonal = 2+l
diagonal^2 = l^2 +w^2
(2+l)^2 = l^2 +w^2
4 +4l +l^2 = l^2 +w^2
4+4l =w^2
l = 59+2w
4+4(59+2w)=w^2
4+236+8w=w^2
w^2 -8w -240 =0
D = 64 +960 = 1024
w_1,2 = (8+/-sqrt1024)/2 = -12 and 20
l=59+2*20=59+40=99
l=99
w=20
hope helped
I think it is the one with the arrow on the 10.
Answer:
A.make calculation easier
Answer:
Step-by-step explanation:
1. The coefficient of 2
is 2. Therefore, the answer is 2 for a. 1 is the coefficient of -x after we add it to the left side. Therefore, b is 1. C is 5, as it is the only whole number.
This means that the answer is a = 2, b =1, c =5.
2. You can simply cancel out both 3s by dividing, which leaves us with 1±9
.
3. The answer is c. Unfortunately, I can't explain that, it's just a well known formula.
I hope this helped!
