Answer:

-1(4c+1)(c-5)

Step-by-step explanation:

First get rid of the negative by factoring out -1, then determine what factors of 5, the constant term(the number without the x), multiply by 4 to add up to -19. The only factors of 5 are 1 and 5, so we will use these. (4c+1)(c-5) can be "foiled" to check our answer.

What are the last 2 digits of 7 to the power of 2018. This question was on a past exam paper.

Xelga [282]

Answer:

Step-by-step explanation:

Try finding pattern of last two digits of 7 to the power of some numbers.

7^1=07

7^2=49

7^3=343

7^4= 2301

7^5= 16807

so , the pattern is, 07,49,43,01

so, if we start writing all numbers from 1 to 2018 , four number in each line, 2018 will fall in the second column.

so it will have 49 as the last 2 digits [by seeing this pattern : 07,49,43,01 ]

A biker travels 5 feet in 0.5 seconds. At this exact speed, how far will the biker travel in a minute?

600 ft. This is because you travel 10 feet per second and there are 60 seconds in a minute. 10 x 60 =600
