Amy and Stephanie were playing a number game. Amy picked a number and told Stephanie that if she added 9 to the number and multiplied the
sum by 4, it would equal 16. Which equation could Stephanie use to find the number, x?
OA. 4(x + 9) = 16
OB.
4(x) + 9 = 16
OC. 4+ (x + 9) = 16
OD. 9(x + 4) = 16

Let X be the number Amy picked.

You add 9 to the number so you have x + 9

That then gets multiplied by 4 to equal 16:

The answer would be A. 4(x+9) = 16

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
