Multiply: (4x – 7)(2x – 9)
Answers
Let's use foil.
First: 4x * 2x = 8x^2
Outside: 4x * -9 = -36x
Inside: -7 * 2x = -14x
Last: -7 * -9 = 63
Now, let's combine these.
8x^2 - 36x - 14x + 63
Finally, we can simplify this
8x - 50x + 63
I hope I helped!

Answer:
the coefficient of the variable in the given expression is, -3
Step-by-step explanation:
Coefficient states that a number which is used to multiply a variable.
For example:
4y
here, y is the variable and 4 is the coefficient.
As per the statement:
Given the expression:
Here, x is the variable
By definition of coefficient, we have;
⇒-3 is the coefficient
Therefore, the coefficient of the variable in the given expression is, -3

The regular polygons could be used to make regular and semi-regular tessellations are equilateral triangle, square and regular hexagon. Therefore, the correct answers are A, B and D.
A regular tessellation is tessellation made up by using only one type of regular polygon. These are made up of completely congruent regular polygons all that connecting vertex to vertex.
Regular polygons have congruent straight sides. When we slide or rotate a regular polygon, the side of the original figure and the side of its translation will match.
Equilateral triangles, squares and regular hexagons are the only regular polygons that tessellate. Therefore, there are only three regular tessellations.
Therefore, the correct answers are A, B and D.

Step-by-step explanation:
square root of 729= 9
9×9=81
Answer:
Step-by-step explanation:
Formula of Volume= - a = side
Therefore since the volume is given you just need to find the side.
729= =
= a
= 9 = a
Now you know that 9 is the side, so using that find the area of one face-
Area of a square= 9 x 9 = 81

Answer : D 7(8-x)-5 = 40
The product of eight minus a number and seven equals forty when decreased by five
Let the unknown number be x
eight minus a number means 8 -x
For product we multiply
The product of eight minus a number and seven
It means the product of 8-x and 7
So expression becomes 7(8-x)
The product of eight minus a number and seven equals forty when decreased by five
To decrease by 5 we subtract 5
7 (8-x) -5 and this equals 40
So equation becomes 7(8-x)-5 = 40
let X = unknown number
eigth minus a number is 8 - x. since the product is seven and eight minus a number then 7 * [8-x] or 7(8-5).
40 is its equivalent when the product is decreased by 5; therefore, 7(8-x) - 5= 40.
