Examine the algebra tiles, Which equation is being modeled?
O 4x + 3 = 4x + 5
O-3x + (-3) = 4x + 5
0 4x + (-3) = 5x + 4
O-3x + 4 = 5x + 4

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
