Hi there! The answer is D. kite.
A kite is a quadrilateral with four sides. These four sides can be grouped into two pairs of two sides. The sides in a pair equal in length. The two pairs of angles are adjecent to each other.
An easy way to recognise this mathematical shape is by comparing it to a kite in real life (a kite is a frame covered with paper or plastic, designed to be flown in the air).
~ Hope this helps you!
Answer:
(2x+3) y (3x+5)
Step-by-step explanation:
For this exercise we have that the volume is
V = 6x ^ 3 + 31X ^ 2 + 53x + 30
H = X + 2
The formula for the Volume its
V = H * L * W
for find L and W (width and length) we divide V / H = L * W
So,
this division is in the attachment
so, L * W = (2x + 3) * (3x + 5)
Mr.Jackson is incorrect because 0.75 is per pound it's not whats added onto 8 pounds
Answer:
Yes.

Answer:
Solution: x = 2, y = -1 or (2, -1)
Step-by-step explanation:
Equation 1: 2x + y = 3
Equation 2: 5x - 2y = 12
Using the substitution method:
Transform the Equation 1 into its slope-intercept form:
2x + y = 3
2x - 2x + y = -2x + 3
y = 2x + 3
Substitute the value of y = -2x + 3 into Equation 2:
5x - 2y = 12
5x - 2(-2x + 3) = 12
5x + 4x - 6 = 12
9x - 6 = 12
9x - 6 + 6 = 12 + 6
9x = 18
9x/9 = 18/9
x = 2
Substitute the value of x = 2 into Equation 2 to solve for y:
5x - 2y = 12
5(2) - 2y = 12
10 - 2y = 12
10 - 10 - 2y = 12 - 10
-2y = 2
-2y/-2 = 2/-2
y = -1
Double-check whether the values for x and y will provide a true statement for both equations:
Equation 1: 2x + y = 3
2(2) + (-1) = 3
4 - 1 = 3
3 = 3 (True statement)
Equation 2: 5x - 2y = 12
5(2) - 2(-1) = 12
10 + 2 = 12
12 = 12 (True statement)
Therefore, the correct answers are: x = 2; y = -1 or (2, -1).
