Answer:
42
Step-by-step explanation:
It's just a distribution property where the given value of each variables (a, b, c, d) are being distributed to the given equation:
7a2-3ac+d2
7(2)(2) - 3(2)(-3) + (-2)(2)
28 + 18 - 4 = 42
A is the easiest way to graph the equation
0.363636363636
<span>..................=<span>411</span></span>
Explanation:
Le <span>x=0.363636363636..................</span>
Now as there are two digits repeating immediately after decimal point, we multiply above by 100 and get
<span>100x=36.363636363636..................</span>
Now subtracting first equation from second we get
<span>99x=36</span> and hence <span>x=<span>3699</span>=<span><span>9×4</span><span>9×11</span></span>=<span>4<span>11</span></span></span>
