Answer:
see below
Step-by-step explanation:
Let's solve your equation step-by-step.
x4−16x2=x2+18
Step 1: Subtract x^2+18 from both sides.
x4−16x2−(x2+18)=x2+18−(x2+18)
x4−17x2−18=0
Step 2: Factor left side of equation.
(x2+1)(x2−18)=0
Step 3: Set factors equal to 0.
x2+1=0 or x2−18=0
x=4.242640687119285 or x=−4.242640687119285
Answer:
x=4.242640687119285 or x=−4.242640687119285

Answer:
(b-3d) (3a+c)
Step-by-step explanation:
factor the expression
Answer:
10% of 440.00=44
1%(÷by 100) of 440.00=4.40
1%=4.40
then do 44+4.40+4.40=52.80(that is 12% comission)
then you add 12% of 440 onto his weekly salary that equals to 492.8
this week he sold 525.000
12%of 525.00=63
then add 63 to 440=503
so Rany eartn $503

Answer:
<u>Solving it mentally</u> :-
It says 25% × 44. When we have a percent, change it to decimal and solve which would be easy to do it mentally.
25% = 0.25
0.25 × 44 = 11 *Answer is bolded.*
<u>Solving it on paper</u> :-
I have attached a picture of me doing it on paper.
Hope this helps, thank you :) !!
