Answer:
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Step-by-step explanation:
Let r be a ratio useful in determining how much of each ingredient Henry needs:
4/8 of the mix is cement, 3/8 is sand and 1/8 is gravel.
4/8 of the total 120 kg must then be 60 kg made up of cement;
3/8 must then be 45 kg made up of sand; and
1/8 must then be 15 kg made up of gravel
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Answer:
(6x^2 - 5)(x^2 + 2).
Step-by-step explanation:
6x^4 - 5x^2 + 12x^2 - 10
= 6x^4 + 12x^2 - 5x^2 - 10
= 6x^2(x^ + 2) - 5(x^2 + 2)
(x^2 + 2) is common so we have:
(6x^2 - 5)(x^2 + 2).
