If 2x2 + 8y = 121.5 and x2 - 8y = 121.5, then x =

The value of x from the given system of quadratic equations is 9.

Given the following data:

To find the value of x, we would solve the system of quadratic equations by using the elimination method:

Adding the two system of quadratic equations together, we have:

x = 9

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

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.
