6m x 10m for the rectangle part.

Then the triangle is base x height/2=3 x 7/2= 21/2

But we have two of the same triangle, so we multiply 21/2 by 2, giving us 21.

21 + 60= 81m^2

Hope you get it!

Answer:

81m²

Step-by-step explanation:

The area of the rectangular part is given by length × width;

i.e 6m × 10m = 60m²

The area of the triangular part is given by \frac{1}{2} × base × height

So it will be \frac{1}{2} × 6m × 7m = 21m²

Total area = Area of the composite figure = 60m² + 21m² = 81m²

Simplify the following expression by combining like terms.
Aleks04 [339]

Answer:

8x^2+3x

Step-by-step explanation:

What I read is 2x+8x^2-4x+5x

combining like terms means putting the terms that have the same variable part together

8x^2 is the only one that doesn't have any terms like it as far as the variable part

so 8x^2+2x-4x+5x

We just need to figure out 2-4+5 which is -2+5=3

So the answer is 8x^2+3x

Decrease £1280 by 60%
klemol [59]

Hi rainy here !!! so lets see lets set up your problem like this                              

X/1280 = 60%/100 so lets cross multiply

100 times X =100X

60 times 1280 = 76800

100X=76800 now lets divide each side by 100

100 divided by 100 = 0

76800 divided by 100 = 768

X=768 

So now we have to subtract to get the total amount so 1280 minus 768 = 512

512 is your answer :)

Hope I helped if u have any questions on how I did your problem feel free to message me or comment on my page bye !!!

Love ~Rainy~
