The sum of twice a number and seven is less than 27 right and solve an inequality statement to figure out the constraints on this number

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

c

step-by-step explanation:

i think because what else can be a sample of every member

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
