Answer:
What is the question?
Step-by-step explanation:
Answer:
:.x=7 ans
Step-by-step explanation:
5x=x+28
5x-x=28
4x=28
x=28/4=7
Answer: x2 + 34x - 13
Step-by-step explanation:
STEP
1
Trying to factor by splitting the middle term
1.1 Factoring x2+34x-13
The first term is, x2 its coefficient is 1 .
The middle term is, +34x its coefficient is 34 .
The last term, "the constant", is -13
Step-1 : Multiply the coefficient of the first term by the constant 1 • -13 = -13
Step-2 : Find two factors of -13 whose sum equals the coefficient of the middle term, which is 34 .
-13 + 1 = -12
-1 + 13 = 12
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
x2 + 34x - 13
Answer: C is the correct option
Step-by-step explanation:
In four hours, a hiker in a canyon goes from 892 ft to 256 ft above the canyon floor.
From the above information,
Total distance travelled by the hiker in moving from 892 ft to 256 ft above the Canyon is 256 - 892 = -636 ft
Speed = distance travelled/time
The hiker’s vertical speed is total distance travelled vertically divided by the time it takes to travel the vertical distance. It becomes
-636/4 = –159 ft/h
