Answer:
Answer:
Step-by-step explanation:
(a) 4x2 -- 3x - 2 = 0
x1,2 = -b ± √b²- 4ac
---------------------
2a
x1,2 = 3 ±√41
--------------
8
(b) (2x - 3)2 = 6
4x² -12x + 9 -6 = 0
4x² - 12 x + 3 = 0

Answer:
1458 sq cm
Step-by-step explanation:
because each dimension of A is 3 tomes each dimension of B, that will mean that both the length and width of B are multiplied by 3 in order to get the length and width of A, so the area of B is length×width=162 and the area of A (in terms of B's dimensions) is 3xlength×3×width=9×length×width=9×162=1458 sq cm
Answer:
slope = -1
Step-by-step explanation:
First, you need to know the slope formula: <u>y2 - y1</u>
x2 - x1
Now recognize the first point (-2,3) as (x1,y1) and the second point (2,-1) as (x2,y2)
Now that you have done that, plug in the numbers into the slope equation.
Which should look like this: <u>-1 - 3</u>
2 - -2
Now that your equation looks like this, recognize the denominator, we should know that a negative plus a negative equals a positive. So instead of subtracting the denominator of the equation, we are going to add the two numbers together, because x1 is negative. Now solve, you should get the answer -1.
<u>-1 - 3</u> <u>-4</u> = -1
2 + 2 4
