G(x)=(-5x-1) (2x+8)
Please help!

Step-by-step explanation:

Step 1:  FOIL out

g(x)= -10x2-42x-8

Step-by-step explanation:

G(x)=(-5x-1)(2x+8)

Open the bracket

G(x)=(-10x2-40x-2x-8)

G(x)=(-10x2-42x-8)

G(x)= -(10x2+42x+8)

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

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
