Evaluate 4.56 × 3.6/ 0.12 and leave you answer in standard form.
Answer:
136.8
Step-by-step explanation:
As per DMAS rule, we can divide first or multiply first. I would choose divide first. Then:
4.56 x 3.6/0.12
= 4.56 x 30.
Since I divided first, the next step is to multiply.
4.56 x 30
= 136.8
Since there is no addition or subtraction happening next, the process ends here and the answer is 136.8.

Please give me brainliest if this was helpful.
The expression value [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10².
To evaluate the expression [tex]4.56 \times \frac{ 3.6}{0.12}.[/tex]
Find the multiplication of the numerator with 4.56 and then divide it by 0.12.
Perform the multiplication first:
4.56×3.6 = 16.416
Now we divide the result by 0.12:
[tex]\frac{16.416}{0.12} = 136.8[/tex]
To express the answer in standard form, we rewrite it as a number multiplied by a power of 10.
In this case, we move the decimal point two places to the right to obtain a whole number:
136.8=1.368×10²
Therefore, the answer to the expression [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10²

Use long division to divide and use the result to factor the dividend completely.
(5x2-13x - 28) + (x – 4)
(5x² - 13x -28)/(x-4) = (x-4)(5x+7) so x = -7/5 and x = 4 are the two factors of the given polynomial.
What is a factor of a polynomial ?The factors of a polynomial are those values of x for which the given polynomial satisfies.
According to the given question we have to divide a polynomial (5x² - 13x -28) by (x - 4).
(5x² - 13x -28)/(x-4) = (x-4)(5x) + (7x - 28).
(5x² - 13x -28)/(x-4) = (x-4)(5x+7).
So, the obtained factor is (5x+7) = 0.
∴ 5x + 7 = 0
5x = -7
x = -7/5 is a factor of the given polynomial and by substituting these value in x.
(5x² - 13x -28)
5(-7/5)² - 13(-7/5) - 28 = 0
5(49/25) + 91/5 - 28 = 0
49/5 + 91/5 - 28 = 0
140/5 - 28 = 0.
28 - 28 = 0
0 = 0 ( hence satisfied that -7/5 is a factor of the given polynomial ).

Step-by-step explanation: An equilateral triangle means all 3 sides are the same length.
A square also have the same length for all 4 sides.
So each side of the square is 6cm, to find the perimeter you do 6*4=24.
then divide the square's perimeter by 3 since triangle have 3 sides. 24/3=8
so each side of the triangle will be 8cm

20. Write the following equation in slop intercept form. -4x-3y=-18.
21. Write the following equation in slope intercept form. -2x+3y=21
please show your work and thank you.
Step-by-step explanation:
slope intercept form y=mx+b
you just need to move the letters and numbers around to match this.
-4x-3y=-18
add 4x to both sides of the equal sign
-3y =4x-18
divide by negative 3 on both sides
y = -4/3x + 6
21. -2x+3y=21
add 2x to both sides
3y = 2x + 21
divide by 3 on both sides
y = 2/3x +7

Answer:
9
Step-by-step explanation:
I've attached a picture, and I hope it's clear and understandable.
Answer: k=9
Step-by-step explanation:
Parallel lines have the same slope. y=mx+b, where m is the slope. The reference line, y = 6x-5 has a slope of 6. The new line must therefore also have a slope of 6. The slope is the Rise/Run, the change in y for a change in x.
The two points on the new line are (10,2k) and (13,4k). Rise over run for this new line is (4k-2k)/(13-10) or 2k/3. This must be equal to 6,
2k/3 = 6
2k = 18
k = 9
