Answer:
161 centimeters
Step-by-step explanation:
To find the total height, we need to find the wait of each individual box. Since we have five boxes stacked up on each other with a height of 115, we can divide 115 by 5 to get 23. Now that we know that each box is 23 centimeters tall, we can multiply that by 2 because 2 more boxes were added, and then add that to 115.
115/5=23
23*2=46
46+115=161
Hope this helps!
X^2 - 8x = (x - 4)^2 - 16
we add 16 to give x^2 - 8x + 16 which is a perfect square
x^2 - 8x + 16 = (x - 4)^2
answer is 16

area of quadrilateral (rhombus)=<u>4square units</u>
<u>:</u>
Solution given:
diagonal 1:AC=2 unit
diagonal 2:BD=4 unit
it looks like a rhombus
so
area of quadrilateral (rhombus)
=½*(diagonal 1*diagonal2)=½(2*4)=4 square units
