Answer:
±7sqrt(2) = x
Step-by-step explanation:
98 - x^2 =0
Add x^2 to each side
98 -x^2 +x^2 = 0+x^2
98 = x^2
Take the square root of each side
±sqrt(98) = sqrt(x^2)
±sqrt(49*2) = x
±sqrt(49)*sqrt(2) = x
±7sqrt(2) = x
Answer:
P = 76 feet, A =338 square feet
Step-by-step explanation:
You got perimeter right, so I assume you don't need explaining.
The area for the rectangle is 270 square feet since 18 x 15 = 270. The area of the triangle is 68 since 17 x 8 is 136, and dividing by 2 gives 68.
Now add 270 and 68, which gives 338 square feet.
Answer:
For the mathematical system that consists of the set of real numbers together with the operations of addition, subtraction, multiplication, and division, the resulting properties are called the properties of real numbers.
Closure Property of Addition also holds in real numbers: The sum of two real numbers is a real number.
multiplication pairs any two real numbers with a real number to become a product a×b
for all real numbers a and b, the difference denoted as a - b is defined by: a - b = a + (-b).
Hence we can also apply the BODMAS rule to the real numbers.
