The answer is n^2+3 or n squared + 3

when it says “three more” it’s implying + 3. When it says “a number squared”, we can use a variable (n) to represent any number and then square it making it n^2.

al we have to do is combine both parts to get n^2+3

Maths * Henry is mixing concrete. To make concrete he needs to mix cement, sand and gravel in the ratio 4 : 3 : 1 by weight. Hen
Mice21 [21]

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.

Simplify: 11^3÷11^3×11^3
Olin [163]

The answer will basically be 11^3, because 11^3÷11^3=1, and 1 times 11^3 equals 11^3, which, if you want to put down the integer answer, would be 1,331.
