<em>To find the answer, just do the inverse. That is, do 4×2. 4×2=8 and 8÷4=2. So A=8.</em>
I thinks its 12% but i could be wrong im new so im trying hard
Answer:
Step-by-step explanation:
sin(195º)= -√6+√2/4
cos(195º)=-√6-√2/4
tan(195º)=2-√3
Answer:
(13 + x) * (15 + x) = 390ft²
18.8 feets ; 20.8 feets
Step-by-step explanation:
Given that:
Initial dimension of patio :
Length (L) = 13 feets
Width ( W) = 15 feets
Initial Area of rectangle :
Length * width = 13 * 15 = 195 feets²
To double the initial area of rectangle :
2 * 195 ft² = 390 ft²
Hence, area of proposed patio = 390ft²
Area of proposed patio:
(13 + x) * (15 + x) = 390ft²
195 + 13x + 15x + x² = 390
x² + 18x - 195 = 0
Using the quadratic equation solver:
X = - 33.77 = - 33.8 or
X = 5.77 = 5.8
X cannot be negative,
Hence, x = 5.8
Length and width of new patio:
Length = 13 + x = 13 + 5.8 = 18.8 feets
Width = 15 + x = 15 + 5.8 = 20.8 feets
Well a prime number is a number that cannot be multiplied by other numbers to equal it. So if it is a product of two other prime numbers it wouldn't be prime. For example, 11 is prime and 11 cannot be a product of two other prime numbers such as 5 and 3 because product means multiply not add which signifies that there is no prime number that is a product (answer to a multiplication problem) of two other prime numbers (that are the factors(
