Sally and joan have been competing to see who can get more steps in each week on their pedometers. during the past week sally has done 65,723 steps and joan has done 90,345. sally is getting tired of losing and so she says that she actually walks more if you look at actual distance. her stride length length is 5.5 inches longer than joans 18 inch stride. if sally walks 70,000 steps next week, how many more steps than sally does joan have to do to make sure she walks furthest distance next week?

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
