Answer:

409 is what I got.

Step-by-step explanation:

361 cm, as the square's area

and 48 as the area for the triangle.

Are you sure those are the answer choices because I'm getting 409.

Answer:

HEY!

THE TOTAL AREA OFTHE FIGURE = AREA OF SQUARE + AREA OF TRIANGLE

= [tex]a^{2}[/tex] +( [tex]\frac{1}{2}[/tex] x b x h)

where , [tex]a^{2}[/tex] = 19 x 19 = [tex]361 cm ^{2}[/tex]

and ( [tex]\frac{1}{2}[/tex] x b x h) = ( [tex]\frac{1}{2}[/tex] x 6 x 19) = ( [tex]\frac{1}{2}[/tex] x 114) = ( [tex]\frac{114}{2}[/tex] ) = [tex]57 cm^{2}[/tex] =

∴ [tex]361 cm ^{2}[/tex] + [tex]57cm^{2}[/tex]  = [tex]418cm^{2}[/tex]

∴ 418 cm²

2x+15=33

Step-by-step explanation:

Let n be the number of days he has been doing sit ups, not counting the first day. Since he does 2 more sit-ups for each day, then the number of additional sit-ups is 2n.

Since he started doing  15 sit-ups on the first day, the total number of sit-ups

after x days would be 2n+15.

Since he did a total of 33 sit ups today, then 2n+15=33

20% - $117.76 = $16.62
and how dose it work?

Answers

Answer:

0.20 - $117.76= $16.62

Step-by-step explanation:

if you  have a percentage you can always turn it into a decimal just put the number behind the period: 70% = .70, 49% = .49%       ....

then you do the rest of the equation and BOOM!

20% - $117.76 = $16.62 = 0.20 - $117.76= $16.62.

Answer:

Answer is below

Step-by-step explanation:

20% - $117.76 = $16.62 = 0.20 - $117.76 = $16.62.

or

20 x 100 / 100 - $117.76 = $16.62

-24 + 9w simplify with distributive factor

Answers

Answer:

3(-8 + 3w)

Step-by-step explanation:

The greatest common factor (GCF) of 24 and 9 is 3. By taking out a 3 from the quantity, you get a -8 from the -24 and a 3w from the 9w. But the 3 doesn't disappear. It is put outside of the quantity to indicate that it has been taken out and can be put back in.

-24+9w

9w-24

= 3(3w-8)
