Answer:

C is correct

Step-by-step explanation:

To factor:

4x^2 + 12x + 5

(4x^2 + 2x)(10x + 5)

2x(2x + 1) + 5(2x + 1)

Then, take the outside numbers make them their own group:

2x + 5

(2x + 5)(2x + 1)

Therefore, it’s (2x + 1)(2x + 5)

12.21 is 3.7 times the number p.
ASHA 777 [7]
P3.7 = 12.21 (p × 3.7 = 12.21)

p÷3.7 = 12.21÷3.7 (p÷3.7 cancels out p×3.7 and leaves you left with the equation p = 12.21÷3.7)

p=3.3

The company, hewerrtt, would like to make letter codes using all of the letters in the word hewerrtt. how many codes can be made
shtirl [24]
<span>If the company, hewerrtt, would like to make letter codes using all of the letters in the word hewerrtt, they would be able to make five codes. Altogether, there are eight letters in the word, but there are duplicates of the letter e, the letter r, and the letter t, so that takes out three possibilities. Three subtracted from eight is equal to five, therefore the company can make five codes using the company name.</span>

Help me with number 10 pleaseeeeeeeeee

Answer:

4' - 9.64

Step-by-step explanation:

Total rise = 2' - 7"

Total run = 3' - 9"

Converting to inches :

1' = 12" ; 1 feet = 12 inches

2' = 2 * 12 = 24"

3' = 3 * 12 = 36"

Total rise = 24" + 7" = 31"

Total run = 36" + 9" = 45"

Length of stringer = hypotenus

Hypotenus = √(total rise² + total run²)

Hypotenus = √(31² + 45²)

Hypotenus = 54.644304"

= 4' - 9.64"
