Best Answer

Do the coefficients first. Since 5 is a factor of 15, it is automatically the GCF. Choose the lowest power of the common variables. The GCF is 5b.

The GCF is 5a.

There is a formula for the "difference of squares." In this case, the answer is (5b - 14c)(5b + 14c)

Kramer's apartment number is 5B

A = (bh)/2Since the base b of the triangle is 5 cm longer than its height, then we can express the height in terms of base. So we have:A = [b(b-5)]/2 (multiply by 2 to both sides)2A = b2 - 5b (substitute 52 for A)104 = b2 - 5b (subtract 104 to both sides)b2 - 5b - 104 = 0 (solve for b using the quadratic formula)b = [5 Â± âˆš[5 - 4(1)(-104)]]/2(1)b = [5 Â± âˆš(5 + 416)]/2 (since the length is always positive)b = (5 + 21)/2b = 13Thus, the base is 13 m long.

You cannot average speeds without knowing how much time is spent traveling at each speed a = time at 40, b= time at 5 Ave Speed = (40a +5b)/(a + b)

4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 3

5b + 5b = 2 x 5b
