The least common multiple of 2, 6, and 8 is 24.
Step-by-step explanation:
step 1. very tough question! you need the slant height (h)
step 2. h = sqr(8^2 + 3^2) = sqr(73) sqr is the square root
step 3. SA = B + ph/2 where SA is the surface area, B is the base area, and p = the lateral perimeter
step 4. we will call the hypotenuse of the right triangle c
step 5. c = sqr(13^2 + 6^2) = sqr(205)
step 6. SA = (1/2)13(6) + (13 + 6 + sqr(205))sqr(73)/2
step 7. SA = 39+ (33.3178)(8.5440)/2 = 181.3336 cm^2.
√30 * √10 = √300
√300 = 10√3
Answer:
-21/5 or -4.2
Step-by-step explanation:
y = 2x + 6
3y - x + 3 = 0
Substitute the value for y from the first equation into the second equation. Solve for x.
3y - x + 3 = 0
3(2x + 6) - x + 3= 0
6x + 18 - x + 3 = 0
5x + 18 + 3 = 0
5x + 21 = 0
5x + 21 - 21 = 0 - 21
5x = -21
x = -21/5 or -4.2
Answer: 3 : 21 3/4
Because it is a enlargement of 3, you need to multiply each side by 3 times.
