Answer:

Step-by-step explanation:

(22/8+3)+(15/8-3)=5, (55/8+3)+(40/8-3)=13

(22/11)+(15/5)=5, (55/11)+(40/5)=13

2+3=5, 5+8=13

It's basically either guess and check, or you can use system of equations (but that would take way more time)

Simplify – 2(7x – 3)

ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive

Dont forget to make this the brainliest answer to help those in need. also add a 5 star and a heart. thanks for the support hope it helped. have a nice day

If a+b=9 and ab=18,find the value of a and b.

Blizzard [7]

Answer:

Given:

a + b = 9

=> a = 9 - b

Given:

a x b = 18

=> (9 - b) x b = 18

=> 9b - b^2 = 18

=> b^2 - 9b + 18 = 0

=> (b - 3)(b - 6) = 0

=> b = 3 => a = 6

=> b = 6 => a = 3

Hope this helps

How do you find surface area of a triangular prism ?

RSB [31]

The formula to find the surface area of a triangular prism is basically finding out the area of one of the faces of a traingle, which is:

 $(base)*(height)/2$

So, basically you take the face of the triangle that your trying to find the surface area of and plug in your values for the base length and height, multiply them together, hen divide that product by 2 to find your surface area :)

Thank you for the question! I hope this helped! Have an amazing day!! :D
