Answer:

Step-by-step explanation:
The number to be added is the square of half of the linear term coefficient. Such coefficient in our case is "10" (the number accompanying the variable x). Then, half of it is 10/2 = 5, and that number squared gives 25.
Therefore, the number to add on bothsides of the equality is 25, which leads to the following:
This matches answer B) of your choices.

Answer:
1240.4 mm²
Step-by-step explanation:
SA of Pentagonal pyramid:
(as)(5/2) + (sl)(5/2)
↑ ↑
base area lateral area
_____________________
a: apothem (in-radius) length, s: side length.
l: slant height.
______________________
Since we are already given the base area which is 440.4 mm². All we need to do is find the lateral area and add both areas together.
Given that the triangular face of the lateral part has a side/base length of 16mm, and a 20mm slant height.
A triangle has an area of ½bh and since there are 5 of these faces total, (5)(½bh) = (5/2)(bh). In a three dimensional perspective, b will be s and h will be l so (sl)(5/2).
With this information the surface area is:
(16)(20)(5/2)mm + (440.4 mm²) →
800 mm² + 440.4 mm² =
1240.4 mm²
Answer:
7
Step-by-step explanation:
Divide the 12 by 4 to see how much one is for.
After you get $3 alk you do is divide the $21 by 3
Answer: It is 326 and 328.
Step-by-step explanation: We know that the numbers must be even and consecutive, so we can figure this problem out by trial and error. Divide 654 by two, and then keep going until you get the proper answer.
