Plug in 3 for x and solve for k.
(3)^2-3k+21=0
3k=9+21
3k=30
k=10
Answer:
105 inches
Step-by-step explanation:
Because the base is a rectangle, that is the best place to start. The first step is to multiply 5 by 6 which results in a base area of 30 inches. Because it is a triangular prism, we then multiply the base and divide by two. The formula for this equation is V=(width*length*height)/2
The final answer is 105
The answer is 43-30x because you always add the parenthesis first which now you have 18+25-10x3 then you calculate the product 18+25-30x. after all that you then add all the numbers and get 43-30x. hope this helps
Answer:
4,600
Step-by-step explanation:
92,000/8= 11500
11500 x 4= 46000 to his wife
11500 for the son
92000-57500= 34500
34500/5= 6,900 each charity
11500-6900= 4600 is how more he is getting than each charity
The square root of 195 is 13. 195 squared (195×195) is 38,025. I do not know which way you needed it but I put both situations just in case.
