Step-by-step explanation:

Since triangle is isosceles then AB = BC

Equate the 2 sides, that is

4x - 21 = 2x - 7 ( subtract 2x from both sides )

2x - 21 = - 7 ( add 21 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7, hence

AB = 2x - 7 = (2 × 7) - 7 = 14 - 7 = 7

BC = 4x - 21 = (4 × 7) - 21 = 28 - 21 = 7

AC = x - 3 = 7 - 3 = 4

Since the triangle is equilateral then all 3 sides are equal.

Equate any 2 sides and solve for x

6x + 1 = 3x + 10 ( subtract 3x from both sides )

3x + 1 = 10 ( subtract 1 from both sides )

3x = 9 ( divide both sides by 3 )

x = 3

HF = 6x + 1 = (6 × 3) + 1 = 18 + 1 = 19 = FG = HG

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

answer: 1 + 1 = 11
