Given: f(x) = x + 2 and g(x) = 3x + 5
(f+g) (x) =
3x + 7
4x + 7
+7
3x2 +7

4x + 7

Step-by-step explanation:

Given :

F(x) = x + 2

G(x) = 3x + 5

(F+G) (x)

= (x + 2) + (3x + 5)

= x + 2 + 3x + 5

= 4x + 7

1. 34

2. 268

3. x=14.4

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
