Answer:

  28x +196 in^2

Step-by-step explanation:

The outside dimension of the square green rug is (x+14), so its area is (x+14)^2. The area of the green band will be the difference between this and the area of the yellow square, (x^2).

  green band area = (x +14)^2 -(x^2) = x^2 +28x +196 -x^2

  green band area = 28x +196 . . . . square inches

Classify the expression below.
babymother [125]

Answer:

D

Step-by-step explanation:

It's a quartic trinomial because its has a fourth degree variable in the expression and only 3 variables in the equation.

2x⁴ - x + 5.

Linear trinomials have 1 degree 3 variables in the monomial. Eg x + y + 2 = 0 is an example of a linear trinomial.

Cubic trinomials have 3 degree and 3 variables in the equation eg = 5x³ + 2x + 1 = 0

Quadratic trinomials is the most common trinomial we deal with everyday eg Ax² + bx + c = 0

Solve for xxx. Write the smaller solution first, and the larger solution second.
____ [38]

Answer:

x=-5\text{ or }x=2

Step-by-step explanation:

We have been given an equation x^2+3x-10=0. We are asked to find the solutions of our given equation.

We will use splitting the middle term method to solve quadratic equation.

We will split middle term of our given equation into parts such that whose product is -10 and whose sum is 3.

We know that such two numbers are 5\text{ and }-2.

x^2+5x-2x-10=0

(x^2+5x)+(-2x-10)=0

x(x+5)-2(x+5)=0

(x+5)(x-2)=0

Using zero product property, we will get:

(x+5)=0\text{ or }(x-2)=0

x+5=0\text{ or }x-2=0

x=-5\text{ or }x=2

Therefore, the solutions for our given equation are x=-5\text{ or }x=2.
