I need help with polynomials i will mark brainiest if your correct multiply the following polynomials

question: -2r(8r+5)
A: -16r^2+5
B: -16r^2+10
C: -16r^2-10r
D: -16r^2-10

question: 4a(a^2+7a+4)
A: 4a+28a^2+16a
B: 4a^3+28a^2+16a
C: 4a^3+44^a
D: 44a^4

question: (2y-3)(3y-2)
A: 6y^2-13y+6
B: 6y^2-13y-6
C: 6y^2+13y-6
D: 6y^2+13y+6

step-by-step explanation:

the answer is 89 d

i took the test

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
