2(3x - 2) - 11x = -5x
6x-2 - 11x=-5x
10x-2
12x
I think it right
If you are trying to figure out what Diego's age is it is 42.
11+ 42= 53
So it's saying to
(5x^2 + 10x - 5) - (7x^2 + 4x - 9)
Collect the like terms
and regroup
(5x^2 - 7x^2) + (10x - 4x) + ( -5 + 9)
Simplify
-2x^2 + 6x + 4
Hope this helps :)
Answer:
Translation 1 unit left
Step-by-step explanation:
we have
f(x)=x
g(x)=(x+1)
we know that
The rule of the transformation of f(x) to g(x) is equal to
f(x) ------> g(x)
(x,y) -----> (x-1,y)
That means----> The translation is 1 unit to the left
Answer:
Step-by-step explanation:
The area of a triangle is related to the base and height by ...
A = 1/2bh
Filling in the given information, we can find the base from ...
199.5 = (1/2)(b)(b+2)
399 = b^2 +2b . . . . multiply by 2
400 = (b +1)^2 . . . . add 1 to complete the square
20 = b +1 . . . . . . . . take the positive square root
19 = b . . . . . . . . . . . subtract 1
h = b+2 = 21
The base of the triangle is 19 feet and the height is 21 feet.
