Mathematics
1 answer:
frez [133]2 years ago
5 0

Answer:

5.8 cm

Step-by-step explanation:

the Pythagorean theorem states that a^2=b^2+c^2, where a is the hypotenuse, and b and c are the legs. Plugging in your values, we get:

4^2 + 4.2^2 = a^2

Simplify: 16 + 17.64=a^2

Simplify again: 33.64 = a^2

Square root both sides: 5.8 = a

Alec is trying to find the surface area of a shoe box. What unit will he use? A) cubic feet B) square feet C) cubic inches D) sq
zysi [14]
The answer to this question would be: <span>D) square inches</span>

In this question, Alex needs to find the surface area of a shoe box. Surface area unit would be represented by "square" because it is 2 dimension. The unit "cubic" is used for volume which was 3 dimension. From here, the option A and C is out because it uses cubic.
The inch unit is better since it was smaller than feet. If you using feet square, the area of the shoe box will be small and it might be less accurate than using inch.

1. Answer is x = 1
Explanation: Rearrange terms
-22 + 8c = 28x - 42
Add 22 to both sides of the equation
8x - 22 = 28x - 42
8x - 22 + 22 = 28x - 42 + 22
Simplify
8x = 28x - 20
Subtract 28x from both sides of the equation
8x = 28x - 20
8x - 28x = 28x - 20 - 28x
Simplify
-20x = -20
Divide both sides of the equation by the same term
-20x/-20 = -20/-20

2. Answer is x = -8
Rearrange terms
-11x - 2 = 6 - 10x
-11x - 2 = -10x + 6
Add 2 to both sides of the equation
-11x - 2 = -10x + 6
-11x - 2 + 2 = -10x + 6 + 2
Simplify
-11x = -10x + 8
Add 10x to both sides of the equation
-11x = -10x + 8
-11x + 10x = -10x + 8 + 10x
Simplify
-x = 8
Divide both sides of the equation
-x = 8
-x/-1 = 8/-1
Simplify
x = -8

3. Answer is x = 7
Rearrange terms
4x + 8 = -13 + 7x
Subtract 8 from both sides of the equation
4x + 8 - 8 = 7x - 13 - 8
Simplify
4x = 7x - 21
Subtract 7x from both sides of the equation
4x = 7x - 21
4x - 7x = 7x - 21 - 7x
Simplify
-3x = -21
Divide from both sides
-3x = -21
-3x/-3 = -21/-3
answer is x = 7

4. Answer is x = -15
Subtract 8 from both sides
2x + 8 = x - 7
2x + 8 - 8 = x - 7 -8
Simplify
2x = x - 15
Subtract x from both sides of the equation
2x = x - 15
2x - x = x- 15 - x
Simplify
x = -15

Tried to be detailed lol hope this helps!
