Agroup of art students are painting a mural on a wall. the rectangular dimensions of (6x+7) by (8x+5) and they are planning the mural to be (x+4) by (2x+5). what is the area of the remaining wall after the mural has been painted?

The area of remaining wall after the mural has been painted is square units.

Step-by-step explanation:

If the dimensions of a rectangle are l and w, then area of rectangle is

The dimensions of wall are (6x+7) and (8x+5). So, the area of wall is

The dimensions of mural are (x+4) and (2x+5). So, the area of mural is

The area of remaining wall after the mural has been painted is

Therefore area of remaining wall after the mural has been painted is square units.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
