Answer:
None of them are perfect
Step-by-step explanation:
(62) 2 is in the list of numbers that are never perfect squares. The number 62 is NOT a perfect square
(61) No, the number 61 is not a perfect square. A perfect square is a number that can be expressed as the product of two equal integers. The only way to accurately calculate if a number is a perfect square is to find the factors.
(63) No, the number 63 is not a perfect square. A perfect square is a number that can be expressed as the product of two equal integers.
(65) No, the number 65 is not a perfect square. A perfect square is a number that can be expressed as the product of two equal integers.
Answer:
First, distribute the -2 to each value in the parentheses.
-2x + 4 = 10
(The 4 is positive because a negative multiplied by a negative is a positive)
Then, subtract 4 from both sides to get rid of it.
-2x = 6
Divide by -2 to get x by itself
x = -3
4(x)=$354.80
x= $88.70
88.7 multiplied by 4 equals $354.80
Answer:
153 degrees is the measure of the supplementary angle
Answer:
48 square units
Step-by-step explanation:
Given that the sides of a triangle are 10,10 and 16.
The triangle with two equal is called and isosceles triangle.
The area of an isosceles triangle is = (b*h)/2
We have to calculate height now,
An isosceles triangle form two right triangles, each with hypothenous equal to 10.
Therfore, the base of one right triangle is 16/2 = 8
Using hypotheneous and base, we can calculate the height of the triangle
=> (10)^2 = h^2 + 8^2
=> 100 = h^2 + 64
=> h^2 = 100 - 64
=> h^2 = 36
=> sqrt(h^2) = sqrt(36)
=> h = 6
So the area is: (6*16)/2 = 48 square units
