Answer:
3x²+8x+5
Step-by-step explanation:
Hi there!
We're given the product of two binomials: (3x+5)(x+1) and we want to express as a trinomial (polynomial with 3 terms)
we can multiply using FOIL; firsts, outers, inners, and lasts
Let's start by multiplying the firsts, which are the first terms in the two binomials, which are (3x+5) and (x+1)
So we'll multiply:
3x*x=3x²
Now we'll multiply the outers, which are the terms on the "outside" in the binomials, which are (3x+5) and (x+1) (remember to include the sign!)
So we'll multiply:
3x*1=3x
then we'll multiply the inners, which are the terms on the "inside" of the binomials, which are (3x+5) and (x+1)
So we'll multiply:
5*x=5x
finally, we'll multiply the lasts, which are the last terms in the binomials, or (3x+5) and (x+1)
So we'll multiply:
5*1=5
now let's add up everything:
3x²+5x+3x+5
we have some like terms that we can combine
3x²+8x+5
Hope this helps!

Answer:
3.2%
Step-by-step explanation:
find dy/dx of ysmall changes of y is 0.04x^5/4small changes of x is 0.032xapproximate % change in x is 3.2%calculate 6 P 6 note n p r equals n Over N - r
The value of 6P6 is 720
How to evaluate the expression?The expression is given as:
6P6
This is calculated using:
[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]
So, we have:
[tex]^6P_6 = \frac{6!}{(6 - 6)!}[/tex]
Evaluate the difference
[tex]^6P_6 = \frac{6!}{0!}[/tex]
As a general rule;
0! = 1
So, we have:
[tex]^6P_6 = 6!\\[/tex]
Expand
[tex]^6P_6 = 6 * 5 * 4 * 3 * 2 * 1[/tex]
Evaluate
[tex]^6P_6 = 720[/tex]
Hence, the value of 6P6 is 720

Theresa has an umbrella stand at the beach. - All of them are blue, except for six. - All of them are yellow, except for six. - All of them are red, except for six. How many blue umbrellas does Theresa have?
Answer:
3 Blue Umbrellas
Step-by-step explanation:
Given
[tex]B \to Blue[/tex]
[tex]Y \to Yellow[/tex]
[tex]R \to Red[/tex]
From the question, we have:
[tex]Y + R = 6[/tex] ---- i.e. 6 are not blue
[tex]B + R = 6[/tex] ---- i.e. 6 are not yellow
[tex]B + Y = 6[/tex] ---- i.e. 6 are not red
Required
The number of blue umbrellas
Make B the subject in: [tex]B + Y = 6[/tex]
[tex]B = 6 - Y[/tex]
Substitute: [tex]B = 6 - Y[/tex] in [tex]B + R = 6[/tex]
[tex]6 - Y + R = 6[/tex]
Collect like terms
[tex]R - Y = 6 - 6[/tex]
[tex]R - Y = 0[/tex]
Rewrite:
[tex]R = Y[/tex]
Substitute [tex]R = Y[/tex] in [tex]Y + R = 6[/tex]
[tex]Y + Y = 6[/tex]
[tex]2Y = 6[/tex]
Divide both sides by 2
[tex]Y=3[/tex]
Recall that: [tex]B = 6 - Y[/tex]
[tex]B = 6 - 3[/tex]
[tex]B = 3[/tex]

Answer:
slope = 1
Step-by-step explanation:
A standard linear function is
y = mx + b
where m = slope, b = initial value
Given y = x + 6
slope m = 1, b = 6
Slope of a line parallel to the given line should have the same slope, therefore slope required is m = 1.
A cone has a radius of 4 units and a height of 6 units.
Answer:
Volume of the cone: 32π cubed unit
Step-by-step explanation:
Volume of cone: V=1/3hπr²
1/3 x 6 x π x 4^2 = 32π
Answer:
The volume of a cone is 100.53. If you want to round it to the nearest one. It's 101.
Step-by-step explanation:
To find the volume. Use the equation V=3.14r^2 h/3
r=4 and h=6 so the equation is V=3.14(4^2) 6/3
V=50.24(6) = 100.53

B. Both sequences are geometric.
C. Sequence 2 is arithmetic and Sequence 1 is geometric.
D. Both sequences are arithmetic.
sequence 2 may be arithmetic because -20 but I can't find out what sequence 1 is
Answer:
C. Sequence 2 is arithmetic and Sequence 1 is geometric.
Step-by-step explanation:
Arithmetic sequence is where number is continuously increased or decreased in same amount we can see that the second sequence is decreases by 20 continuously
Geometric sequence is where a number is continuously divided or multiplied by same number
we can see that the first sequence is continuously multiplied by (-2)

What is the slope and y-intercept of this equation?
y=2-9x
m=
b=
Answer:
Slope (m) is the number being multiplied by x (make sure you include the sign in front of it).
y- intercept (b) is the number other than the x
Step-by-step explanation:
Answer:
The slope is -9 and the y intercept is 2
Step-by-step explanation:
Write the equation in slope intercept form
y= mx+b where m is the slope and b is the y intercept
y = -9x+2
The slope is -9 and the y intercept is 2

If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of sides? A.20cm B.16cm C.22cm D.23cm
Complete question:
If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of the third sides? A.20cm B.16cm C.22cm D.23cm
Answer:
B. 16 cm
Step-by-step explanation:
Given;
two lengths of the triangle as 15 cm and 4 cm
The length of the third side of the triangle must be less than the sum of the two given sides.
Length of third side < 15 cm + 4 cm
Length of third side < 19 cm
The only option less than 19 cm is B. 16 cm
Therefore, the correct option is B. 16 cm

Mean median and mode??? Help
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest.
