Find value of x also the answer choices are

a. 62.5
b. 9.65
c. 71.35
d. 103.25

D.103.25

Step-by-step explanation:

To find the value of x, you need to know that the height of the donkey and the cactus are proportional and that the shadow of the donkey and cactus are also proportional to each other. Thus, you need to create a proportional and cross multiply to find the value of x.

x/59 = 7/4

After you cross multiply, the equation should look like this:

4x=413

Finally, you divide both sides or numbers by 4 to get 103.25 as your answer! Hope this helps!

what is the answer to this

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,
