Answer:

1) ∠A = 90º Square

2) ∠A = 140º Parallelogram

3) ∠A = 90º Rectangle

4) ∠A = 95º Rhombus

5) ∠A = 60º Trapezoid

6) ∠A = 41º Parallelogram

Step-by-step explanation:

There just some points I want to state:

Rhombus is a quadrilateral with all sides being equal and opposite sides being parallel. Also, the opposite angles are equal, and the the diagonals bisect each other at right angles (90º).

In order to find the angles, just consider:

Sum of internal angles = 360º

You may also note the complementary and supplementary angles.

Answer:

6x^3+11x^2-14x+12

Step-by-step explanation:

We just simply add like terms (terms with same power of x):

$6x^3+(4x^2+7x^2)+(-5x+-9x)+(2+10)$

Like terms are in brackets now

So you just simplify now to give you:

$6x^3+11x^2-14x+12$

Answer:

(-7, 8)

step-by-step explanation:

original coordinates of B: (-9, -8)

if translated two units horizontally, there will be change in x axis

new coordinates: (-9+2, -8) → (-7,-8)

if reflected over x-axis, use the formula: (x,y) → (x, -y)

new coordinates: (-7, -(-8)) → (-7, 8)
