Answer:
a1 = 4 , an = -
Step-by-step explanation:
The first term is already given to us and a common ration between the terms is 4 and it is oscillating between positive and negative values so it must be mulitplied by a negative.
Associative, Commutative, Multiplicative, and distributive:)
Answer:
A. 13m
Step-by-step explanation:
To find the area of a square you multiply Length by the Height. Since squares have equal length sides the number has to be the same for the length and the height.
13 x 13 = 169
Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!

Answer:
<em>m<ZXY - m<WXZ = m<WXY
</em>
Step-by-step explanation:
given:
point Z is in the interior of <WXY creating XZ.
<em>if m<WXZ = 20
</em>
<em> m<WXY = 100
</em>
find:
what would equation would you set up to find the missing angle measure?
solution:
Since Z is interior of <WXY
<em>m<ZXY - m<WXZ = m<WXY
</em>
<em><WXY = 100 - 20 = 80°
</em>
therefore, the equation would be <em>m<ZXY - m<WXZ = m<WXY </em>
