Answer:
x=3
Step-by-step explanation:
If k is between J and L, then
JK + KL = JL
2x+11 + (3x) = 13x-13
Combine like terms
5x +11 = 13x -13
Subtract 5x from each side
5x-5x+11 = 13x-5x-13
11 = 8x-13
Add 13 to each side
11+13 = 8x-13+13
24 = 8x
Divide by 8
24/8 = 8x/8
3 =x
Answer:
The answer is $28.56
Step-by-step explanation:
To find the 2% sales tax, you need to multiply the 2% or 0.02 by 28.
Doing this will give you 0.56.
Then you add 0.56 to 28 to get 28.56, hence, $28.56 is the total cost.
Hope it helps!
(8-3)²-(5-2)²
Follow the PEMDAS
P-Parenthesis
E-Exponents
M/D-Multiplication/Division
A/S-Addition/Subtraction
clear the numerals in the parenthesis:
(5)²-(3)²
Now do the exponents:
=25-9
=16
Its just: (5)²-(3)²
Consider this solution, if it is possible, check the result:
1) if to divide polynomial 'x³-3x²-6x+8' on 'x+2' result is: x²-5x+4, then x³-3x²-6x+8=(x+2)(x²-5x+4);
2) x²-5x+4=(x-1)(x-4), then
3) x³-3x²-6x+8=(x+2)(x-1)(x-4).
4) zeros are: -2;1;4. Other zeros are: 1 and 4.
Answer: 1;4.
1. Answer = About 1451.42 m³
- First, we need to find the volume of the cube:
- Formula: πr²h
- Volume = π * 3² * 50 = 1413.72 m³
- Second, we need to find the volume of the cone:
- Formula: (πr²h)/3
- Volume = π * 3² * 4 = 37.69 m³
- Third, we need to add these two volumes to find the total volume of the figure.
- 1413.72 m³ + 37.69 m³ = 1451.42 m³.
2. Answer <em>= </em>960 m³
- Formula: (1/2(b*l)) * 20
- First, we need to find the area of the base (1/2 * b* l).
- 1/2 * 8 * 12 = 48.
- Second, we need to multiply the area of the base by the height to get the volume.
- B * h = 48 * 20 = 960 m³.
