ill add you if you follow my t i k t o k(:
4: <BEC and <ECB are supplementary.
False, <em><BEC and <ECB are angles of triangle BCE and sum of two angles of a triangle can't be equal to 180 ( two angles of a triangle can't be supplementary). </em>
5: C is the midpoint of BD.
False: <em>It's not given C is the mid-point. So, we can't assume C is a mid point.</em>
6: <BCE and < ECD are a linear pair.
True,<em> because <BCE and < ECD are two angles on a common point on a line.</em>
7: <ABE and <EBC are complementary.
True, <em>because <ABC is a right angle and <ABE + <EBC = <ABC.</em>
For number thirteen I believe it is Alkali metals,and btw this should be in science not math.
The length of MN is 4. Subtract MP by NP.
12-8=4
$1442
Because I=prt but this equation is only for simple interest the variables then would be interest=principle*time*rate
Your time is 24 month which is equal to 2 years, the principle is 1400 and the rate is 1.5% but you would change it to a decimal which would be 0.015 because a percent is out of a 100
So the equation is Interest=1400*0.015*2
The interest is $42 and then it asks what would be in her account if she does not make any deposits or withdrawals so you would add the interest to her account and that would be $1442.
The other type of interest is compound and it has a different equation
