Add it all together and divide it by 2 the answer is 10
If xy=0 assume that at leas 1 is zero
set it to zero
0=2a^2-16a+32
undistribute 2
0=2(a^2-8a+16)
2*0=0 so assume
a^2-8a+16=0
factor
(a-4)(a-4)=0
set to zero
a-4=0
a=4
when a=4, equation equals zero
Answer:
70.574
Step-by-step explanation:
7.1 × 9.94= A
9.94
7.1
-------
70.574
A= 70.574
(when multiplying decimals do not line up the dot and solve it as if there was no decimals point. when you get your answer count the amount of digits on the right side of the number going to the left on your answer.
in this case there are three digits on the right side of the decimals you count three spaces to the left of your answer wich is 574. put the decimal point infront of the 5 and you get you answer. 70.574
It should be the second image on this list. I hope this helps! ^^
