The table needs to have a 90 degree angle the three sides are 6 inches 8 inches and 9 inches can it fit
spin [16.1K]

Answer:

It can't fit.

Step-by-step explanation:

If it has a right angle then c^2 = a^2 + b^2 where c = the longest side.

c^2 = 9^2 = 81

a^2 + b^2 = 6^2 + 8^2 = 100

- so It cant have a right angle.

Fofino [41]

The amount John have left after purchase is $10.8.

<h3 /><h3>Amount John have left</h3>

John  earned $45.90 during the summer break.

He used 1 / 6 of the money to buy trading card. Then he used the following amount to buy the trading card.

  • 1 / 6 × 45.90 = $7.65

Then, he used 3/5 of the remaining amount to buy a sketchbook, and also spends $4.50. Therefore, the total he spends can be computed as follows:

  • 3 / 5 × (45.90 - 7.65) + 4.50 = 22.95 + 4.50 = $27.45

So, He spent

  • $7.65 on trading cards
  • $22.95 on sketch book
  • $4.50 on comic book.

The amount he has left = 45.90 - 7.65 - 22.95 - 4.50 = $10.8

F(x) = x2 + 3x + 2 is shifted 2 units left. The result is g(x). What is g(x)?
Lesechka [4]

Answer:

D. g(x) = (x + 2)^2 + 3(x + 2) + 2

Step-by-step explanation:

To shift the function to the left by 2 units, x is replaced by x - (-2) = x+2. Then you have ...

... f(x+2) = g(x) = (x+2)² +3(x+2) +2 . . . . matches selection D
