Answer:

Step-by-step explanation:

Using the area model and standard algorithm, we have:

                332   (tenths)

         <u> ×       21  </u>

                332

        <u>      664     </u>

        <u>      6972  </u> tenths = 697.2

<u />

              30      +      3      tenths

     1       300           32         332

    20     600           64         664

33.2 × 21 =<u>    30    </u> × <u>    1     </u>  =  <u>      30     </u>

Factor 21c+24.<br> Write your answer as a product with a whole number greater than 1.<br> use ()
Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

21c+24=3\left(7c+8\right)

Step-by-step explanation:

Given the expression

21c+24

Determining the factor

21c+24

  • Rewrite 24 as 3 · 8
  • Rewrite 21 as 3 · 7

so the expression becomes

21c+24=3\cdot \:\:7c+3\cdot \:\:8

Factor out the common term 3

             =3\left(7c+8\right)

Therefore, the required answer as a product with a whole number greater than 1 will be:

21c+24=3\left(7c+8\right)

Angle K = angle M

(4x-1)=(2x+27)

4x-2x=27+1

2x=28

x=14

K=4x-1 then 4(14)-1
55 degrees
M=2x+27 then 2(14) +27
55 degrees
K+M+L =180
55+55+L=180
110+L=180
L=70 degrees
Therefore K=55 degrees M=55 degrees L=70 degrees

F
Burka [1]

Answer:

12

Step-by-step explanation:

F \alpha \frac{1}{d^{2} }

F = \frac{K}{d^{2} }

When F = 18; d = 2

18 = \frac{K}{2^{2} }

18 = \frac{K}{4}

Cross multiply;

18 x 4 = K

72 = K

There the equation connecting F and d^{2} is

F = \frac{72}{d}

Now, Find F when d = 6

All you do is to substitute d = 6 in to F = \frac{72}{d}

F = \frac{72}{6}

Therefore;

F = 12

Please mark me brainiest if correct.
