Answer:
x = -0.22 or x = -2.28
Step-by-step explanation:
2x^2 + 5x + 1 = 0
You use the quadratic formula: -b ±√5² - 4 x 2 x 1 ÷ (2 x 2)
-5 +√17 ÷ 4 = -0.22
-5 - √17 ÷ 4 = -2.28

Select all factors of the following polynomial: 5p3 + 45p2 + 40p
Answer:
[tex]\huge\boxed{5p;\ (p+1)}[/tex]
Step-by-step explanation:
[tex]5p^3+45p^2+40p=5p(p^2+9p+8)=5p(p^2+p+8p+8)\\\\=5p\bigg[p(p+1)+8(p+1)\bigg]=5p(p+1)(p+8)\\\Downarrow\\\boxed{5p};\ \boxed{(p+1)};\ \boxed{(p+8)}[/tex]
the factors for the given expression are
[tex]5p, p+1, p+8[/tex]
Given :
Given expression is [tex]5p^3 + 45p^2 + 40p[/tex]
Lets factor the given trinomial by factoring out GCF that is greatest common factor
Lets find out GCF from the given expression
all the terms are divisible by 5 and also we have 'p' in common
so GCf is 5p
[tex]5p^3 + 45p^2 + 40p\\5p\left(p^2+9p+8\right)\\[/tex]
Now we factor [tex]\left(p^2+9p+8\right)[/tex]
Product is 8 and sum is 9
So factors are 8 and 1
[tex]5p\left(p^2+9p+8\right)\\5p\left(p+1\right)\left(p+8\right)[/tex]
So the factors are
[tex]5p, p+1, p+8[/tex]

Quinn likes to knit hats and mittens for friends and family. Last fall, she knitted 4 hats and 3 pairs of mittens, which took a total of 56 hours. This fall, she knitted 3 hats and 1 pair of mittens, which took a total of 27 hours. If each hat and each pair of mittens takes the same amount of time to knit, how long does it take Quinn to knit a hat and a pair of mittens?
Answer:
hats = 5
mittens = 12
Step-by-step explanation:
hats = h
mittens = m
Uknown:
- How many hours per hats
- How many hours per mittens
Known:
- How many hours in total
- How many pairs of mittens made
- How many pairs of hats made
4h + 3m = 56
3h + 1m = 27
3h + m = 27
m = -3h + 27
4h + 3m = 56
4h + 3(-3h + 27) = 56
4h - 9h + 81 = 56
-5h = 56 - 81
-5h = -25
-5h/5 = -25/5
-h = -5
-h/-1 = -5/-1
h = 5
3h + m = 27
3(5) + m = 27
15 + m = 27
m = 27 - 15
m = 12
Check: h = 5, m = 12
4h + 3m = 56
3h + 1m = 27
4h + 3m = 56
4(5) + 3(12) = 56
20 + 36 = 56
56 = 56
3h + 1m = 27
3(5) + (12) = 27
15 + 12 = 27
27 = 27

What transformation for Rectangle A would result in Rectangle B?
A
reflection across the X-axis
B
reflection across the y-axis
c
translation, 4 units up
D
translation, 2 units down
Answer:
I think A I'm not sure tho
In the transformation of rectangle A, a reflection is across the X-axis. The correct option is A.
What is a reflection?A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a set of fixed points known as the hyperplane, also known as the axis or plane of reflection. The mirror image of a figure in the axis or plane of reflection is the image produced by a reflection.
Given image is having a rectangle A which is having reflection across the X-axis. The meaning of the reflection is that the figure will have an image of itself across the x-axis.
Therefore, in the transformation of rectangle A, a reflection is across the X-axis. The correct option is A.
