Step-by-step explanation:
9) C
10) B
11) (b-5)(b+8)
12) (7w - 2)²
13) 14(5x + 2)(3x - 1)
14) (4h - 1) and (h + 6)
15) 3 and (a - 2) and (a + 8)
16) 5 and (4w - 1) and (w + 2)
79,350 cm
Explanation:
115x115=13,225 (this is the area of one side)
13,225x6=79,350(a cube has 6 sides)
9514 1404 393
Answer:
(h, k) = (9, -8)
Step-by-step explanation:
The function g(x) is "vertex form" for a quadratic whose vertex is (h, k). We are told the vertex is (9, -8), so we have ...
(h, k) = (9, -8) . . . . the values of h and k
No, they are not like terms because they cannot be added together. 5x^2 is squared, whereas 2x is not. Though they both have x variables attached to them, they are not like terms because one is squared and the other is not. Examples of like terms include 5 and 8, 4y and 7y, 8z^2 and 10z^2.
Hope this helps!! :)
Answer:
Step-by-step explanation:
Multiply the row of the first matrix to the column of the second matrix
simplifying them we get
