Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.

PLEASE HELP ME OMG X
Answer:
Answer: 544
Step-by-step explanation:
The Surface Area of a Cuboid
Given a cuboid (rectangular prism) of dimensions x,y, and z, the surface area is calculated as follows:
[tex]S=2(xy+yz+xz)[/tex]
The dimensions of a given cuboid are x=28 cm, y=4 cm, z=5 cm, thus:
[tex]S=2(28*4 + 4*5+ 28*5)[/tex]
[tex]S= 2*272 = 544[/tex]
The surface area is [tex]544 cm^2[/tex]

Answer: x= 10
Step-by-step explanation:
Same side exterior angles sum to 180.
Using this axiom we can say that
142+ (3x+8) = 180
Add like terms on the left side
150+ 3x = 180
Subtract 150 from both sides
3x = 30
Divide both sides by 3
X= 10

What are the x- and y-intercepts?
0,3
1,20
3,36
5,28
7,0
The required x-intercept is (7, 0) and the y-intercept is (0, 3).
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
To find the x-intercept, we need to find the point at which the graph intersects the x-axis. This occurs when the y-coordinate is zero.
The x-intercept is therefore (7, 0).
To find the y-intercept, we need to find the point at which the graph intersects the y-axis. This occurs when the x-coordinate is zero.
The x-intercept is therefore (0, 3).
Thus, the x-intercept is (7, 0) and the y-intercept is (0, 3).

Round 576.558 to the nearest tenths place
Answer:
576.6
(look at the number by the 10th place and round)
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Option A is the correct answer.
What is place value?The place value of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 = thousandths place value
We have,
576.558
The number in the tenth place is 5 bolded underscore.
576.558
Now,
The next value is 5 which is greater or equal to 5 so we will change the tenth place value 5 into 6.
If the next value was 4 or less we will keep the tenth place value 5 as 5.
Now,
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Thus,
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
