Rewrite 4x^2-3x+9=2x+1 as 4x^2-5x+8 = 0
Here, a = 4, b = -5 and c = 8. Then,
5 plus or minus sqrt (25 -4(4)(8) )
x = ------------------------------------------------------
8
5 plus or minus sqrt (-103)
= --------------------------------------
8
5 plus or minus i*sqrt(103)
Then x = ----------------------------------------
8
= ---------------------------------------------
8
= ----------------------------
Answer:
c
Step-by-step explanation:
because the answer
and its proof
Okay, So We Need To Solve For X, So We Can Solve The Expression:
6x - 5.
Lets Begin.
-17x - 9 = 8.
So, We First Need To Add 9 To Both Sides.
-17x = 8 + 9
8+9 = 17.
-17x = 17
Divide.
-17x/-17 = 1x = x.
So:
X = 17/-17
17/-17 = -1
So:
X = -1
Now, Plug In The Value For The Expression.
6 * (-1) - 5
6 * (-1) = -6
(-6) - 5 = -11.
So, Our Value For 6x - 5 Is -11.

Answer:
Area of wall = 360 ft²
Step-by-step explanation:
Given:
One part of wall (Rectangle) = 16ft x 18ft
Another part of wall (Triangle) = 8ft x 18ft
Find:
Area of wall
Computation:
Area of wall = Area of rectangle + Area of triangle
Area of wall = (l x b) + (1/2)(b)(h)
Area of wall = (16 x 18) + (1/2)(8)(18)
Area of wall = 288 ft² + 72 ft²
Area of wall = 360 ft²
