An integer greater than -2
goblinko [34]
On the number line below, there are arrows pointing to the left and to the right. The arrow that is pointing to the left has numbers below them; those numbers are negative numbers, including -2. 0 is mutual, meaning that it is a positive and a negative number. The numbers to the right are positive numbers. Positive numbers are greater than negative numbers, therefore, any number after 0 is greater that is greater than -2.

Please help with 8 and 10 ..
Natalka [10]

Answer:

8) Parallelogram.

10) Point W.

Step-by-step explanation:

8) Give another name of plane V.

As shown the plane represents A flat shape with 4 straight sides where opposite sides are parallel and also opposite sides are equal in length.

So, plane V represents parallelogram

10) Name a point that is not coplanar with R, S and T.

Coplanar points are the points which all lie in the same plane.

So, as shown:

R, S and T are coplanar points, they all lie in the plane V

So, the point which doesn't lie in the plane V is the point W

So, <u>the point W</u> is not coplanar with R, S and T.

Solve for all values of x by factoring.<br> x^2 + 4x – 30 = -3x
vichka [17]

Answer:

{x}^{2}  + 4x - 30 =  - 3x \\{x}^{2}  + 7x - 30 = 0 \\  {x}^{2}  - 3x + 10x - 30 = 0 \\ x(x - 3) + 10(x - 3) = 0 \\ (x - 3)(x + 10) = 0 \\  \boxed{x = 3} \\  \boxed{x =  - 10}

<h3><em><u>x=3 or x=-10</u></em> is the right answer.</h3>
