(x - 4)(2x + 3)
Using foil:
2x^2 + 3x - 8x - 12
Simplify.
2x^2 - 5x - 12 is the product after using FOIL.
Do the steps of x and y. And see where they hit each other
Answer:
Solution given:
now
f(x)+g(x)=
....(1)
now
factoring x²+6x-40
we get
x²+10x-4x-40
x(x+10)-4(x+10)
(x+10)(x-4)
now substituting in equation 1 ,we get
f(x)+g(x)=
taking l.c.m
=
=now
opening bracket
=
So
answer is :
B. 
Answer:
x = 8 units
Step-by-step explanation:
Note that the ratio of the middle-length legs is 12/18, and that of the shortest-length legs is x/12.
Then:
12 x
----- = -----
18 12
... which, through cross- multiplication, becomes 18x = 144. Then x = 8 units
Answer:
2(n - 6)
Step-by-step explanation:
Difference = n - 6
Twice the Difference = 2(n - 6)
