r-ruslan [8.4K]3 years ago
3 0

Answer:

h² + 9h + 23

Step-by-step explanation:

Given

f(x) = x² + 3x + 5

To evaluate f(3 + h) substitute x = 3 + h into f(x), that is

f(3 + h) = (3 + h)² + 3(3 + h) + 5 ← expand (3 + h)² using FOIL

            = 9 + 6h + h² + 9 + 3h + 5 ← collect like terms

            = h² + 9h + 23

Joseph has 48 comic books. He sold one-fourth of his collection to his friend. He brought twice the number of comic books as he
Tresset [83]

Answer:

108

Step-by-step explanation:

Given that Joseph has 48 comic books.

As he sold 1/4 of his collection to his friend, so

The number of books, Josef sold = 1/4 x 48 = 12.

The number of remaining books, Josef has = 48 - 12 = 36.

As he brought twice the number of comic books as he has now, so,

the number of comic books, Josef brought = 2 x 36 = 72.

Now, total number of comic books, Josef has = 36 + 72 = 108.

Angle x is conterminal with angle y. If the measure of angle x is greater than the measure of angle y, which statement is true r
fiasKO [112]

9514 1404 393

Answer:

  x = y + 360n, for any positive integer n

Step-by-step explanation:

Since x is greater than y, something must be added to y to get x. Angles have the same co-terminal ray at multiples of 360°. Then the amount added to y must be some multiple of 360°:

  x = y + 360n . . . . . for positive integer n

Write the equation x² + 6x + y² – 8y = 19 in standard form.
kirza4 [7]

Answer:

Formula used :

  • <u>x²+2xy+y²</u><u> </u><u>=</u><u> </u><u>(x+y)²</u>
  • <u>x²-2xy+y²</u><u> </u><u>=</u><u> </u><u>(x-y)²</u>

→{x}^{2}  + 6x +  {y}^{2}  - 8y = 19 \\  ({x}^{2}  + 2.3.x +  {3}^{2} ) +({y}^{2}  - 2.4.y +  {4}^{2} ) = 19 +  {3}^{2}  +  {4}^{2}  \\  {(x + 3)}^{2}  +  {(y - 4)}^{2}  = 19 + 9 + 16 \\  \boxed{ {(x + 3)}^{2}  +  {(y - 4)}^{2}  = 44}✓

  • <u>3) (x+3)²+(y-4)²=44</u> is the right answer.
