LCD of 2 16 and 8 is definitely 16.
1/2 = (1/2)*(16/16) = 8/16
3/16 = (3/16)*(16/16) = 3/16
7/8 = (7/8)*(16/16) = 14/16
Use the Pythagorean theorem: a² + b² = c²
c = hypotenuse (which means) = 53
a and b are equal to the side length
So a = 21.
Use the formula and solve.
21² + b² = 53²
441 + b² = 2809
b² = 2368
b = 48.66210024238575 or 8√37
(2x+2)(10x^2 - 6x + 8) =
2x(10x^2 - 6x + 8) + 2(10x^2 - 6x + 8) =
20x^3 - 12x^2 + 16x + 20x^2 - 12x + 16 =
20x^3 + 8x^2 + 4x + 16 <==
Answer:
3.25
Step-by-step explanation:
it is shrinking by a factor of 4 so every number is 4 times smaller and 13 divided by 4 will give you 3.25
Answer:
$193.67
Step-by-step explanation:
Let x = shirts
Let y = trousers
Let z = hat
4x + 4y + 2z = 660
9x + 9y + 6z = 1399
Divide the second equation by 3.
3x + 3y + 2z = 466.33
Subtract both equations
.
4x + 4y + 2z = 660
3x + 3y + 2z = 466.33
x + y = 193.67
So 1 shirt and 1 trouser will be $193.67
