Answer:

C. 4yd * 3ft/yd * 12in/1ft * 2.54cm/1.in = 365.76cm

Step-by-step explanation:

First you change 4 yards into feet (By multiplying the 4 yard by 3 ft/1yd)

then you convert 12 feet into inches (By multiplying the 12 feet by 12in/1ft)

after you convert 144 inches to cm (By multiplying the 144 in by 2.54 cm/1in)

you’ll have the value in cm. Which is 365.76.

Solve for x. 7(x - 3) = 4(x + 5) x =1/11 x =1/3 x =41/11 x =41/3
marin [14]
To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
   
                                          7x - 21 = 4x + 20

Transpose all the terms with x and the constant on either sides of the equation,
 
                                           7x - 4x = 20 + 21
  
                                        3x = 41   ;    x = 41 / 3

Thus, the answer is x = 41/3 which is fourth among the choices.

Factor completely 9x2 42x 49. (3x 7)(3x − 7) (9x − 7)(9x − 7) (3x 7)(3x 7) (9x 7)(9x 7).
sweet-ann [11.9K]

Factors of the given expression by splitting middle term of expression9x^2+42x+49 will be (3x+7) and (3x+7).

Given expression is

9x^2+42x+49

<h3>What is a factor?</h3>

A factor is a number that divides another number leaving no remainder

After we split 42x into 21x each,

The expression looks like,

9x^2+21x+21x+49

3x(3x+7)+7(3x+7)\\

Taking 3x+7 as common

(3x+7) (3x+7)

So factors will be (3x+7) and (3x+7).

Therefore,

Factors of the given expression 9x^2+42x+49 will be (3x+7) and (3x+7).
