Hello :
answer : a
because : f(2i) = (2i)^4 -45(2i)² -196 = 16(1)-45(-4)-196...... ( i²=-1)
= 16+180 -196 =196-196 =0
same solution : f(14i)=f(-14i)=0
Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
3x - 4 = 2x + 1
Step 2: Solve for <em>x</em>
<u>Subtract 2x on both sides:</u> x - 4 = 1
<u>Add 4 on both sides:</u> x = 5
Answer:
no problem :)
Step-by-step explanation:
You multiply the number of cars(bottom row) by 4 to get the number of tires(top row) so if there are 4 cars then there will be 16 tires. If you think about it, there are 4 tires on a car so you would multiply the number of cars by 4 to get the number of tires
