An art gallery has a total of 11 paintings by a particular artist; of these, 5 are oil paintings and 6 are watercolour paintings. The art gallery is asked to provide a special exhibition of this artist’s work but is restricted to showing only 5 paintings. Find the number of combinations

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
