2(11x-6)-18 is equal to 22x-30

Yes they are equal

Step-by-step explanation: First you have to solve 2(11x-6)-18:

2(11x-6)-18

22x - 12 - 18

22x - 30

They equal!

0

THE RIGHT HAND SIDE IS EQUAL TO THE LEFT HAND SIDE.

Step-by-step explanation:

2(11x-6)-18 is equal to 22x-30

the above question can as well be expressed as

2(11x-6) - 18 = 22x -30

the next thing is to apply the BODMAS(BRACKET, OF, DIVISION, MULTIPLICATION, ADDITION , SUBTRACTION.) rule by first opening the bracket

22x - 12 -18 = 22x -30

We will proceed to collect the like terms

22x -22x = -30+12+18

0 = -30 +30

0=0

the answer is = 0

THEREFORE THE RIGHT HAND SIDE IS EQUAL TO THE LEFT HAND SIDE.

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
