Answer:
4x^2+4x-4
Step-by-step explanation:
8x^2 + 3x - 4x^2 + x - 4
= 8x^2 - 4x^2 + 3x + x - 4
= 4x^2 + 4x - 4
Answer
x = 3981071.7055
y = 3981.0717
x > y
Step by step explanation
First let's find the value of x and y by taking anti - log.
log X = 6.6
X = log^ -1 (6.6)
X = 3981071.7055
Similarly,
log Y = 3.6
Y = log ^(-1) 3.6
Y = 3981.0717
Once we found the values of X and Y , we can easily compare them.
Here x > y
Hope you will understand the concept.

To find the total area of this figure, it would be easiest to find the area of the left part (rectangle) and then find the area of the right part (triangle), and then add the two area values together.
First, we will find the area of the rectangle, using the formula A = lw, where l is the length of the rectangle and w is the width of the rectangle.
The length of the rectangle is 13 cm and the width is 9 cm. If we substitute in these values into our equation, we get:
A = (13cm)(9cm)
A= 117 cm^2
Next, let’s find the area of the triangle, using the formula A=(1/2)bh, where b is the base of the triangle and h is the height.
The base of the triangle is 11 cm and the height of the triangle is 5 cm (found by subtracting 13-8 as seen in the figure). If we substitute in these values and simplify, we get:
A=1/2(11cm)(5cm)
A=1/2(55cm^2)
A=27.5 cm^2.
When we add together the area of the rectangle with the area of the triangle, we will get the total area of the figure.
117 cm^2 + 27.5 cm^2 = 144.5 cm^2
Your answer is 144.5 cm^2 or the first option.
Hope this helps!
Answer:
4.5 Cubic Feet
Step-by-step explanation:
1. You want to find the volume of the box. (Length x width x height)
2.5 x 2 x 1.5 = 7.5
2. The present has a volume of 3 cubic feet, so you would subtract that from the volume of the box.
7.5 - 3 = 4.5
3. The volume of the empty space in the box is 4.5 cubic feet.
Hope this helped! :)
