Answer:
The area of the square is 225 cm².
Step-by-step explanation:
Since the geometric figure has a shape of a square, which is a special form of rectangle that has all the sides with the same length, then it's surface area is given by the following formula:
area = length*width = length^2
We can solve for the area by applying the data from the problem, we have:
area = (15)^2
area = 225 cm^2
The area of the square is 225 cm^2.
Integers are whole numbers, whether they are negative or positive. They cannot be decimals, or fractions.
The numbers listed are 8, -4.1, -9, 1/6, 1.75 and 22.
The only integers are 8, -9, and 22; the other numbers are rational numbers.
answer : 40
Step-by-step explanation:
√32 × 5√2
= √32√2 = √64
= √64 × 5
= √64 = 8
= 8× 5
= 40
Answer: 640 (B)
Step-by-step explanation:
The explicit formula
an = -5 × ( -2 )(n - 1) bearing in mind that n = 8
Therefore, putting n = 8 - 1, = 7
-5 × -2(7) raised to the power of 7
an = -5 × -128
= 640
