P = 2L + 2W L = W + 6 P = 2(W + 6) + 2W P = 2W + 12 + 2W P = 4W + 12
5 + 2(3x + 4) + x 5 + 6x + 8 + x 5 + 8 + 6x + x 13 + 7x Stop Don't go any further. That's the 11th commandment: Thou shalt not combine unlike terms.
Paul has a long drive. If Shelly waits up she better have some snacks 4*65 + x = 500 The x stands for the number of miles left to go 270 + x = 500 Subtract 280 from both sides x = 500 - 270 x = 230
Just so you know if he keeps going at 65 mph the amount time will be 230/65 = 3.53 hours.
a) To find the missing side length on triangle A, we can use the Pythagorean theorem.
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5 cm
5 and 12 = 5 and 12
b) The two triangles are congruent because they have two side lengths in common. If at least two side lengths are the same on two triangles, then they are congruent. In addition, these triangles have one angle in common as well.
