Factorise x^2 - 7x + 12

Answers

Answer 1
Answer:

Answer:

= (x-4)(x-3)

Step-by-step explanation:

Firstly, put the pronumeral in the brackets [(x)(x)].

Then, place the signs in the right positions, the sign of the constant number (12) is a positive (+), therefore the two signs must be the same. The sign of the -7x is negative (-). Place these in the brackets [(x-)(x-)].

Next, think of the factors of 12 that add up to 7 {(3 and 4) 3x4 is 12 and 3+4 is 7}. [(x-4)(x-3)].

Have a nice day!!!!!!! :-)

Chris brought 2 umbrellas each costing $13.He brought 3 ponchos each costing $4 how much did Jack spend in all

Answers

We know that 2 umbrellas each cost $13, so 13*2=26 and we also know that he brought 3 ponchos that cost $4, so 4*3=12. The question asks how much did Jack spend in all. In all means add, so we add 26+12 which equals 38. So, Jack spent $38.
Jack would have spent a total of 38 dollars all together

Least common denominator finds a common number in the denominator of two fractions. 14 can be factored out as 2*7 and 7 is obviously 7*1. So the least common denominator could come from both numbers that have common denominators. In order to attain a common denominator, you need to multiply the 7 by 2 to make 14. So the least common denominator is c. 14.
the correct answer for that is c. otherwise 14

A manufacturer buys bolts from a supplier. The bolts cost 0.17 cents each, but the manufacturer made a deal with the supplier and get 4000 bolts for $595.50. To the nearest cent, how much money does the manufacturer save on 4000 bolts with this deal?

Answers

845 cents Because 4,000 x 0.17= 680. 680-595.50= 84.05. 84.05 is 845 cents.
He save exactly 845 cents because 4,000 X 0.17 = 680  680-595.50=84.5 which is equal to 845 cents.
