Answer:
To transform the given expression to the sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.
Thus, the answer to this is (4x^2)^3 + 3^3
Answer:
26,please check my calculations in explanation.
Step-by-step explanation:
3+3+2+2+4+4+4+4
<span>If Tanya’s three items (x) cost the same as Tony’s four items (y), 3x = 4y. Y is 2.25 less than x, so: 3x = 4x - 4 x 2.25. 3x = 4x - 9. 3x + 9 = 4x. 9 = x. Therefore, y = 9 - 2.25. x = 9 and y = 6.75. Three times 9 and four times 6.75 is 27. Tanya’s items cost $9 each and Tony’s cost $6.75.</span>
Answer: <em>-18</em>
Step-by-step explanation:
We know that Kayla’s grade was lowered every time she was late to class. Taking this into consideration, we multiply -3 and 6 (beacuse she was late to class 6 times; 3 is negative because her grade is decreasing) which results in -18.
The change is Katja’s grade is -18% or points.
