6x + 9
I hope this helps!
Answer:
= 6x +9
Step-by-step explanation:
1. you need to multiply -3 by x² + 2x - 3
so you got -3x² -6x + 9
2. Then, you need to multiply 3 by (x²+4x)
= 3x² + 12x
3. -3x² - 6x + 9 + 3x² + 12x
4. then you need to solve with the same
= - 3x² + 3x²
= 0
= - 6x + 12x
= 6x
5. lastly you will got the answer.
# = 6x +9

In one baseball season, Peter hit twice the difference of the
number of home runs Alice hit and 6. Altogether, they hit
18 home runs. How many home runs did each player hit
that season?
Answer:
Alice hit 10 home runs.
Peter hit 8 home runs.
Step-by-step explanation:
Let [tex]p[/tex] be the number of home runs Peter hit.
Let [tex]a[/tex] be the number of home runs Alice hit.
[tex]p=2(a-6)\\a+p=18\\\\a+2(a-6)=18\\a+2a-12=18\\a+2a=30\\3a=30\\a=10\\\\a+p=18\\10+p=18\\p=8\\\\p=2(a-6)\\8=2(10-6)\\8=2(4)\\8=8[/tex]

Identify the domain of the function shown in the graph.
Answer:
C. x is all real numbers.
Step-by-step explanation:
Since the domain is likely infinite, then the domain must be all real numbers so x is all real numbers.

Answer:
C
Step-by-step explanation:
Matrices can be multiplied together if the number of columns in the first matrix equals the number of rows in the second matrix.
A is of order (3 × 2) and B of order (2 × 3 )
Since the 2 in the first and the 2 in the second match , the matrices can be multiplied
The resulting matrix is of order (3 × 3 )
This is obtained from the first 3 in order of A and the second 3 in order of B
Then AB is defined and the resultant matrix is of order 3 × 3

Find the midpoint of the two points (8,-2) and (-4,6).
a (9,7)
b (2,2)
c (9,2)
d (2,8)
Answer:
B
Step-by-step explanation:
To do that we use the formula: (x1 + x2) / 2 and (y1 + y2) / 2 to get (x,y) coordintaes of the mid-point
Therefore
(8 + (-4) ) / 2 , (-2 + 6) / 2
= 2,2

The diagonals of a rhombus are 30cm and 16cm. Find its area, the length of a side and its perimeter.
Answer:
Area = 1/2 × product of diagonalsso area = 1/2 × 30 ×16 = 240 cm²
also diagonals bisect each other at right angles so 1/2×30= 15cm,, 1/2× 16 = 8cm
therefore by pythagoras theorem,
[tex] {15 }^{2} [/tex]+ [tex]{8}^{2} [/tex]= [tex] {side}^{2} [/tex][tex] \sqrt{289 = side} [/tex]
side = 17
Perimeter = 4×17 =68 cm.

what is the Domain of this?
Answer: The domain is 3/7, -6, and 4.
Step-by-step explanation:
In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 (since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.
As the other answer mentioned, x = -6 and x = 4 are not in the domain, since they both make the denominator equal to zero, and thus the overall expression undefined. But x = 3/7 is allowed, since f (3/7) = 0.
Every other real number is also acceptable.
In interval notation, the domain is then
[tex](-\infty,-6) \cup (-6,4) \cup (4, \infty)[/tex]
X/3 = -7.x/3 is a fraction
Lets simplify

Cancel x/3[tex]\\ \sf\longmapsto -7[/tex]
Hence its not a fraction

Which group of integers is in order from least to greatest?
A -12, -18-, -20, -24
B -20, -12, -24, -18
C -24, -18, -12, -20
D -24, -20, -18, -12
Answer:
D
Step-by-step explanation:
its not a because 12 is the greatest because its closest to zero
it not b because 24 is farthest from zero not 20
and its not c because 12 goes after 20 not 12,20
so the answer is d

Here is a sketch of Noah's bedroom
He wants to create a scale drawing of his bedroom to show to his designer.
The actual length of wall A is 3.5 m.
He uses a scale of 1 m = 6 cm to draw his scale drawing.
How long should the length of wall A be on the scale drawing?
Answer:
21cm
Step-by-step explanation:
for every 1m, it is 6cm on the paper. thus, your answer would be 3.5÷1 which is 3.5
then multiply 3.5 by 6 which is 21
why is x^4 the largest perfect square of x^5
Answer:
Step-by-step explanation:
Because x^5 has 5 members. When you group them into 2 members each, there is one x left over. This is most easily seen if you try it with numbers.
The clearest way is to pick something that is not a perfect square to start with.
6 * 6 * 6 * 6 * 6
6^2 is a perfect square. It is grouped into 2 groups. Each one is a 6
So 6^2 = 36. 36 is a perfect square.
You should note that 6 ^3 is not a perfect square. One of the 6s is unmatched and you get a fraction when you square root 6^3.
6 * 6 * 6 = 216. The square root of 216 is 14.697... which goes on forever.
6^4 is a perfect square.
6^4 = 1296 The square root of 1296 is 36.

Solve for X. Show your work
1/2x - 1/4 = 3/5x + 2
Answer:
[tex]x = - \frac{45}{2} [/tex]
Step-by-step explanation:
[tex] \frac{1}{2} x - \frac{1}{4} = \frac{3}{5} x + 2[/tex]
[tex]20( \frac{1}{2} x - \frac{1}{4} ) = 20( \frac{3}{5} x + 2)[/tex]
[tex]20 \times \frac{1}{2} x - 20 \times \frac{1}{4} = 20( \frac{3}{5} x + 2)[/tex]
[tex]10x - 20 \times \frac{1}{4} = 20 \times \frac{3}{5} x + 20 \times 2[/tex]
[tex]10x - 5 = 20 \times \frac{3}{5} x + 20 \times 2[/tex]
[tex]10x - 5 = 4 \times 3x + 20 \times 2[/tex]
[tex]10x - 5 = 4 \times 3x + 40[/tex]
[tex]10x - 5 - 12x = 40[/tex]
[tex]10x - 12x = 40 + 5[/tex]
[tex] - 2x = 40 - 5[/tex]
[tex] - 2x = 45[/tex]
[tex]x = - \frac{45}{2} [/tex]
