Which statements are true about David's work? Check
all that apply
The GCF of the coefficients is correct.
The GCF of the variable b should be b4 instead of
62.
The variable c is not common to all terms, so a
power of c should not have been factored out.
The expression in step 5 is equivalent to the given
polynomial.
In step 6, David applied the distributive property.

i think this could be a possible answer (1 / 84) -1

good luck! : d

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

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.

sorry i just need to anwers this to get points
