The triangles in each pair are similar.
Solve for x.
A) 10
B) 6
C) 8
D) 4

D

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

50(19x + 5) = 4050 ( divide both sides by 50 )

19x + 5 = 81 ( subtract 5 from both sides )

19x = 76 ( divide both sides by 19 )

x = 4 → D

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
