answer = the elder bother is 17 and the younger one is 15
constructive odd integers= 15 and 17
17×15= 255
255+38 = 293
Square root of 293 = 17
Answer:
10 hours, 30 minutes.
Step-by-step explanation:
Distance ÷ Speed = Time
525 ÷ 50 = 10.5
Answer:
4 right angles
Step-by-step explanation:
a straight light intersects another straight line= creating 4 right angles
Answer:
See explanation

Step-by-step explanation:
1. Make sure that the trinomial is written in the correct order - the trinomial must be written in descending order from highest power to lowest power. In you case, the trinomial must be written as

2. Decide if the three terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer.
In your case, coefficients 2, 5 and 3 do not have common factors, so go to the next step.
3. Multiply the leading coefficient and the constant, that is multiply the first and last numbers together:

4. List all of the factors from step 3 and decide which combination of numbers will combine to get the number next to x:

5. After choosing the correct pair of numbers, you must give each number a sign so that when they are combined they will equal the number next to x and also multiply to equal the number found in Step 3:

6. Rewrite the original problem with four terms by splitting the middle term into the two numbers chosen in step 5:

7. Now that the problem is written with four terms, you can factor by grouping:

Coefficient: 20 or 5
Variable: c or w
Constant: 95.50
Pt B: 20(5) + 5(20) + 95.50
100 + 100 + 95.50
295.50
Pt C:The coefficient of c would change to 10
