If your trying to figure out (x) then the answer would be 7 because 7 times 2 is 14 and then 14 minus 3 would be 11
Answer:
B) Inside the nucleus of an atom are protons and electrons.
Explanation:
Inside the nucleus of an atom are protons and neutrons. Electrons orbit (kind of?) away from the nucleus.
To find the area of a square with it's diagonal, there's actually a formula = (1/2)d², but here's how to do it if you don't have the formula:
The diagonal <em>c</em> separates the square into two of the same triangles. Therefore, we can apply Pythagorean Theorem
a²+b²=c² ← Since this is a square, a=b is a must
a²+a²=c² ← Combine like terms, and plug 26 in for c
2a²= 26² ← 26²=676, then divide 2 on both sides
a²= 676/2
a²=338 ← We can just stop here! Since <em>a </em>is a side of the square, therefore the area of a square = a²
Answer: 338 units²
132, if you add four to 50, and keep going until you get to 20
A parallelogram is a flat shape with opposite sides parallel and equal in length. The diagonals of a parallelogram bisect<span> each other. In simpler words, they intersect halfway point. We calculate as follows:
</span>d2 = √<span>2a^2 + 2b^2 - d1^<span>2
</span></span>d2 = √2(7)^2 + 2(9)^2 - 14^2
d2 = 8 inches
