Evaluate 8 − m n + p 2 8− n m +p 2 8, minus, start fraction, m, divided by, n, end fraction, plus, p, squared when m = 8 m=8m, equals, 8, n = 2 n=2n, equals, 2, p = 7 p=7p, equals, 7.

Step-by-step explanation:

Given

Required

Evaluate

To solve this;

we simply substitute the values of m, n and p in the given expression

In other words; we replace m, n and p with their actual values;

becomes

Solve fraction

Take square of 7

Add result

The expression has been evaluated and the result of is 53, provided that m = 8, n = 2 and p = 7

step-by-step explanation:

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
