x²(2 - 7x) (-x+2)
Expand the following exercise
Answer:
Step-by-step explanation:
Use FOIL method
(2 - 7x)(-x + 2) = 2*(-x) + 2*2 + (-7x)*(-x) + (-7x)*2
= -2x + 4 + 7x² - 14x {Combine like terms}
= 7x² - 14x - 2x + 4
= 7x² - 16x + 4
x²(2-7x)(-x + 2)= x² (7x² - 16x + 4)
= x²*7x² - 16x * x² + 4x²
[tex]7x^{2+2} -16x^{1+2} + 4x^{2}\\\\= 7x^{4} - 16x^{3} + 4x^{2}[/tex]

Answer:
2) (see image below)
3) x = 8
side(s) = 74
4) x = 10
EF = DE = 67
base = 31
Step-by-step explanation:
For No. 2, if you draw out two triangles with the corresponding angles, you can make it a lot easier. See the image below:
For No. 3, it is given that it's an equilateral triangle, meaning all sides and angles are congruent. So:
12x – 22 = 10x – 6 = 7x + 18
Instead of using all three at once, you can use any two. I'll be using:
12x – 22 = 10x – 6
2x = 16
x = 8
Plugging x in, we can get all the sides, because this is an equilateral triangle:
12x – 22
12(8) – 22
96 – 22
74
For No. 4, it is given that the triangle is an isosceles triangle where DE ≅ EF, so:
8x – 13 = 5x + 17
3x = 30
x = 10
Plugging in x for one of the congruent sides and the base, you can get your needed side length values:
8x – 13
8(10) – 13
80 – 13
67
x + 21
10 + 21

A. The number of hours depends on the number of boxes manufactured.
B. The number of boxes manufactured depends on the number of hours.
C. The number of pens depends on the number of boxes manufactured.
D. The number of pens depend on the number of hours.
Answer:
B. The number of boxes manufactured depends on the number of hours.
Step-by-step explanation:
The graph shows that as more time passes, more boxes are being manufactured. Therefore, the number of boxes relies on the number of hours.

Seven times the first number plus six times the second number equals 31.
- Three times the first number minus ten times the second number is 29.
WHAT ARE THE TWO NUMBERS
The first number will be [tex]\frac{11}{2}[/tex] and the second number will be [tex]-\frac{5}{4}[/tex].
Let the first number be x and the second number be y.
According to the question,
Since seven times the first number plus six times the second number equals 31. So,
[tex]7x+6y=31.......(1)[/tex]
Similarly,Three times the first number minus ten times the second number is 29.So,
[tex]3x-10y=29.......(2)[/tex]
Multiplying equation (1) by 3 and equation (2) by 7, we get
[tex]21x+18y=93[/tex]
[tex]21x-70y=203[/tex]
Now subtracting both the equations we get,
[tex]88y=-110[/tex]
[tex]y=-\dfrac{110}{88}[/tex]
[tex]y=-\dfrac{5}{4}[/tex]
putting the value of x in equation (1) we get,
[tex]7x+6\times-\dfrac{5}{4} =31[/tex]
[tex]7x-\dfrac{15}{2}=31\\[/tex]
[tex]7x=31+\dfrac{15}{2}[/tex]
[tex]7x=\dfrac{77}{2}[/tex]
[tex]x=\dfrac{11}{2}[/tex]
Hence the first number is [tex]\frac{11}{2}[/tex] and the second number is [tex]-\frac{5}{4}[/tex].
