Answer:
this is the answer I hope it helps
x= 4,-1
2/3(x)-(-1/3(x)-4)=?
?=0
1÷3 = 0.3
2/3(x) - 0 -1/3(x) = ?
? = 0
2 ÷ 3 =.67
4(3)/ 3
your "x" becomes a negative
So, (-x) - 12 / 3 - 2/3(x)
we get the "12" from multiplying 4(3) from each other
Your like term of this problem▶ -x + 12
2(x) - (-x) - 12 / 3
3(x) + 12
x + 4 = 0
-4 -4
---- ----
4x - 4
4x - 4 = 0
We have one solution to this equation
So, therefore your answer for this question is:
x = -4
Answer:
18
Step-by-step explanation:
The formula you should use is Area = 1/2bh, in other words, area equals half times base times height. Now, substitute everything in, the equation should now be 221.16 = 1/2*b*29.1. This simplifies into 221.16 = 14.55b, now divide 14.55 on both sides, which leaves us to 15.2 = b. However, don't forget the units, which the answer (length of base) should be 15.2 in.^2.
