The solutions to the equations are:
x = 21,
x = 7,
4 * 7 = 28,
3³ - 2³ = 19, and 30 - 2 = 28.
We have,
x + 7 = 28
To solve for x, we can subtract 7 from both sides of the equation:
x + 7 - 7 = 28 - 7
x = 21
So, the solution to the equation x + 7 = 28 is x = 21.
2x + 14 = 28
To solve for x, we can subtract 14 from both sides of the equation:
2x + 14 - 14 = 28 - 14
2x = 14
Next, we divide both sides of the equation by 2 to isolate x:
2x/2 = 14/2
x = 7
Therefore, the solution to the equation 2x + 14 = 28 is x = 7.
4 * 7 = 28
This equation is already solved.
The product of 4 and 7 is 28.
So, the equation 4 * 7 = 28 is true.
3³ - 2³ = 28
To solve this equation, we need to evaluate the exponentials:
3³ - 2³ = 27 - 8 = 19
Therefore, the equation 3³ - 2³ = 28 is not true; the correct value is 19.
30 - 2 = 28
This equation is already solved.
The difference between 30 and 2 is indeed 28.
So, the equation 30 - 2 = 28 is true.
Thus,
The solutions to the equations are:
x = 21,
x = 7,
4 * 7 = 28,
3³ - 2³ = 19, and 30 - 2 = 28.

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

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

Determine whether each sequence is arithmetic or geometric. Sequence 1: –10, 20, –40, 80, ... Sequence 2: 15, –5, –25, –45, ...
A. Sequence 1 is arithmetic and Sequence 2 is geometric.
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)
