# Find the sum of these polynomials. (х2 +х+ 9) + (7х2 + 5) = а. 7х2+x+ 14 7х2+x+4 ос. 8х2 +х+4 od. 8х2+x+ 14 submit

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

)

triangle abd and cba are similar,

(2)

triangle cad and cba are similar,

)

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

Solution:

Given given expression to calculate is:

We have to add both the polynomials

Addition of two polynomials involves combining like terms present in the two polynomials

We have to add like terms

Like terms means "the terms having same variable and same exponent"

And we have to add the constants
