Evaluate the following expression: 4(3,5) -2(7,-2) a. (-1,18) b. (-2,24) c (-4,7) d. (16,16)

B. (-2, 24)

Step-by-step explanation:

First, you need to multiply the vectors by the scalars. To do this, you simply multiply the scalar by each component of the vector:

And then you add the vectors by adding the corresponding components:

So the answer is option B.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

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
