Factor each trinomial completely.<br> 4x^2 - 25b^2 and x^2 - 81

GenaCL600 [577]

Step-by-step explanation:

4x2 - 25b2

We can solve it by the squares so

(2x - 5b) (2x + 5b)

2) x2 - 81

The same case is here so

(x - 9) (x + 9)

Joe has 5 more than twice as many calculators as John. Write an algebraic expression. *

yarga [219]

Answer:

B. 5 + 2p

Step-by-step explanation:

<u>Let's simplify the problem:</u>

Joe has 5 + more than 2(P) as many calculators as John.

*We'll be using Addition and Multiplication operations.

If Joe has 5 more than 2 times the amount of calculators, the algebraic expression will be:

$5 + 2p$

p represents John's amount of calculators.

5 + (5 more than) 2(P) Twice the amount of calculators John has.

Bogdan [553]

Answer:

50cm

200cm

50cm^2

Step-by-step explanation:

The big square is divided into 4 with a side length of 25cm. 2 small square side lengths make up the big squares.

25 * 2 =

50cm

50 + 50 + 50 +50 =

200

15 +2

8 + 2

17 * 10 = 170

15 * 8 = 120

170-120 = 50

50cm^2
