Please, do not post more than 1 or 2 questions at a time. Out of courtesy I will address one of your six questions here:
<span>2x + 4 = 3(x – 2) + 1
You are to solve this for x.
1) perform the multiplication: </span><span>2x + 4 = 3x - 6 + 1
2) combine like terms: 4+6-1 = x
3) solve for x: x = 11
4) check: Is 2(11) + 4 = 3(11-2) + 1 true?
Is 22+4 = 33-6 true? NO. Try again, looking for the mistake:
</span><span>2x + 4 = 3(x – 2) + 1 => 2x + 4 = 3x - 6 + 1
4 = x - 5
9 = x
Check: Is 2(9) + 4 = 3(9-2) + 1 true? Is 18+4 = 22 true? YES.
The solution to #1 is x = 9 (answer).
Submit your other questions separately, please.

Answer:
6
Step-by-step explanation:
15-8 =7 as LHS is 7 so RHS must also be 7 so at RHS 6+1 =7
We must look first for the properties given, so we have:
Rectangle - four sides, two pairs of opposite sides are parallel, four right anglesQuadrilateral - a four-sided figureRhombus - four sides, two pairs of opposite sides are parallel, all sides equal
So we're finding for a shape that has four sides that are all equal, with two pairs of parallel sides, and has four right angles. So from this description, we can say that it is a square. Squares have two pairs of parallel sides (like a rhombus and rectangle), four right angles (like rectangles), and four sides that are equal (like a rhombus). A square is also both a rectangle and a rhombus.
Answer:
No, Dale Isn't correct because 3:5 is greater than 2:10
Step-by-step explanation:
3:5 and 2:10 is the same as in 
and 
First Find the least common denominator or LCM of the two denominators:
LCM of 5 and 10 is 10
Next, find the equivalent fraction of both fractional numbers with denominator 10
For the 1st fraction, since 5 × 2 = 10,
Likewise, for the 2nd fraction, since 10 × 1 = 10,
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
Hence, is <u>Greater than </u>
Hence, 3:5 is <u>Greater than </u>2:10
Answer:
4
Step-by-step explanation:
The given polynomial is :
p(x) = -2a⁴+8a³-9a
We need to find the degree of the polynomial.
Degree of the polynomial = degree is the value of the greatest exponent.
Here, the maximum value of the exponent is 4 in -2a⁴.
It means,
Degree of the polynomial = 4
