Hello guys! I am Fabiona. I like solle exercises. Below you have a problem from me. It is for 6th grade students. It can also be solved by equation. 3 friends spent a total of 400 many to buy teaching aids. The second spends 10 many more than the first, while the third 20 many more than the second. How much did each
of them spend?

b

step-by-step explanation:

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

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.
