What is the value of p in the equation 4p + (10+5p) = 7?

-1/3

Step-by-step explanation:

First off, you need to add the common variables like 4p and 5p which is 9p.

Now we have,

9p + 10 = 7

      -10   -10

9p = -3

Here were going to have to isolate the variable, the variable really hates that 9 so let's divide them.

9p/9 = p so now "p" is single. That was our goal but what's it's value?

We're going to need to divide -3/9 to get a really long decimal so we can just simplify it to -1/3. And that's why -1/3 is the answer.

Hope that helps and have a great day!

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
