I think the answer is 1/2 (x^2 + 11x + 30) but see the discussion below.
Step-by-step explanation:
I can hardly read the signs between the dimensions. This is my best guess.
Area Shaded = Area Rectangle - Area Triangle
Area Rectangle = (x + 5)(x + 6)
Area Triangle = 1/2 (x + 5 ) ( x + 6)
Area shaded = (x + 5)(x+6) - 1/2 (x + 5)(x + 6)
Area shaded = 1/2 (x + 5)(x + 6)
Area Shaded = 1/2 (x^2 + 11x + 30)
If the second factor (x + 6) is really x - 6 then the area of the shaded area is 1/2 (x+5)(x - 6)
Area Shaded = 1/2 * (x^2 - x - 30)

Solve for each variable X and Y.
Answer:
x=5 and y=7
Step-by-step explanation:
The opposite parallel sides of any rhombus are going to be equal.
a.) Knowing this you take (x+14) and make it equal to (5x-2). Then you subtract the x from (x+14), and add the 2 from (5x+2), making the new equation 16=4x. You divide 4 by x and by 16, getting the final simplified answer of x=4.
b.) Using the same method you take 3y-3 and set it equal to (2y+4). Then you subtract the 2y from (2y+4) and add the 3 from (3y-3) to bother sides. Now you have your new equation and answer being y=7.
a.) x+14 = 5x-2
b.) 3y-3 = 2y+4

For which value of x will the rational expression below be undefined? Check all that apply. (x-5)(x+2)/x+1 A. -5 B. -1 C. 1 D. 5 E. -2 F. 2
Answer:
B. -1Step-by-step explanation:
Given expression:
(x-5)(x+2)/(x+1)This is undefined when the denominator is zero:
x + 1 = 0x = -1Correct choice is B
Answer:
Answer :-[tex] \sf \: \dfrac{(x - 5)(x + 2)}{x + 1} [/tex]
Now,
Taking denominator as 0
x + 1 = 0
x = 0 - 1
x = -1

each side of a triangle is nine inches long. find the perimeter
The triangle in which the side are nine inches long has a perimeter of 27 inches.
Perimeter of a triangle
The perimeter of a triangle is the sum of the length of the whole side.
The triangle have three sides and the perimeter is the sum of the whole sides.
According to the question, the triangle has the whole sides as 9 inches.
This means the triangle is an equilateral triangle.
Therefore,
length of side = 9 inches
perimeter = 9 + 9 + 9
perimeter = 27 inches

please help(: ( 8th grade lesson)
Step-by-step explanation:
Since angle 1 is on a straight line and we know that angle 4 is 160, and a straight line has a sum of 180 degrees, simply subtract 160 from 180 to get angle 1.
Angle one would be 180-160 = 20
Since the sum of angles in a triangle is 180 and we already know 2 of them, angle 1 is 20 and angle 3 is 30, just add them together and then subtract that from 180. 20 + 30 = 50, and 180 - 50 = 130.
So in conclusion:
Angle 1 is: 20
Angle 2 is: 130
Find AE if AB=12, AC=16, and ED=5.
Answer:
the ratio is 12:16=3/4
So AE:5+AE=3/4
4AE=15+3AE
AE=15
Step-by-step explanation:
The length of the line segment AE is 15 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points.
Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know, In a triangle if one segment is parallel to one side of a triangle divides the other two sides in the ratio of their corresponding lengths.
Given, AB = 12, AC = 16 and ED = 5, hence BC = AC - AB = 4.
Therefore, AB/BC = AE/ED.
12/4 = AE/5.
4AE = 60.
AE = 15 units.
