Help plz Simplify the expression below. If your answer is not a whole number, enter it as a fraction in lowest terms, using the slash mark (7) as the fraction bar.
-4 • (7-4) - 6 \ 6 +7

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

the answer is y = 11.54

hope this : )

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
