Ab + c^2 when a = 7, b = -3, and c = -4​

-21 + 16 = -5

Step-by-step explanation:

7(-3) + (-4)

Multiply the 7(-3), and the answer will be negative because we are multiplying a pos to a neg.

-21 + (-4)

Do the exponent, this will be a positive because the exponent is by two so we multiply (-4) by (-4) so the signs match.

-21 + 16

Now solve.

-21 + 16 = -5

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
