The temperature is -2c. If the temperature rises by 15c what is the new temperature?

13c

Step-by-step explanation:

-2+15=13

13c

13c

Step-by-step explanation:

To find the new temperature, add 15 to -2, since the temperature rose by 15c and was originally -2c.

-2 + 15

= 13

So, the new temperature will be 13c.

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
