Answer:
{x,y,z} = {-22/13,29/13,6/13}
37. we know the perimeter of the Box is 30 and two sides are five each so 30-10 is 20 divided by the other two equal size is 10 .
38, The dimension of other in the lids are 10 and a five to find the area if you multiply 10×5 = 50 and you only have to cover 42 sq cm so no you don't have enough eight more sq cm.
Answer:
x = -4
Step-by-step explanation:
8x = 8 + 2(x-10) + 3x
simplify
8x = 8 + 2x - 20 + 3x
simplify again
8x = 5x - 12
subtract 5x from both sides
3x = -12
divide both sides by 4
x = -4
