Answer:
7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.
On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.
For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.
Answer:
1.
7x+11y-(5x+6y)
7x+11y-5x-6y
2x+5y
2.
13x+12y-(6x+2y)
13x+12y-6x-2y
7x+10y
3.
8x+8y-(4x-2y)
8x+8y-4x+8y
4x+16y

The length of a rectangle is 3ft less than twice the width, and the area of the rectangle is 77ft^(2). Find the dimensions of the rectangle.
Answer:length=11 and the width is 7
Step-by-step explanation:
To find the area of a rectangle it’s widthxlength and the only numbers that make up 77 are 11 and 7 and 77and 1. So it would have to be 11 and 7 also if you plug it in (2(7)-3=11 and that works. Hope this helps <3

Answer:
The measure of angle a is 45 degrees.
Step-by-step explanation:
Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:
90 + a + a = 180
2a = 180 - 90 = 90
a = 90/2 = 45
a = 45
