Step-by-step explanation:

Step 1: Define

Identify

2(x - 3) = (x - 1) + 7

Step 2: Solve for x

Combine like terms [Addition]: 2(x - 3) = x + 6
[Distributive Property] Distribute 2: 2x - 6 = x + 6
[Addition Property of Equality] Add 6 on both sides: 2x = x + 12
[Subtraction Property of Equality] Subtract x on both sides: x = 12

How do I solve these equations

Sever21 [200]

You need to know the properties of each function.
Tan is opposite (y) over adjacent (x). Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3 so it is located in quadrant 1.
The side of the triangle must be Adjacent=3 opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is
$\sqrt{\frac{1+cos}{2} }$
By following the formula, cos=3/5 then:
$\sqrt{ \frac{1- \frac{3}{5} }{2} }$ Multiply everything (inside the square $\sqrt{ \frac{5+3}{10} }$ root) by 5
$\frac{2 \sqrt{2} }{ \sqrt{10} }$
$\frac{2 \sqrt{20} }{10}$ Then just simplify
$\frac{ \sqrt{20} }{5}$ The answer is Square root of 20 over 5

A plant that manufactures metal plates has a quality control team to check that the plates are the right size. A rectangular pla

Kamila [148]

Answer:

Given the size of rectangular plate in advertisement = 5 cm by 3cm.

Given the condition for length should be = 0.25 of 5 cm

Step-by-step explanation:

Now, have to write the inequality from the given data.

Therefore, 5- 0.25 ≤ L ≤ 5+.25

4.75 ≤ L ≤ 5.25

We know that the area of a rectangle = Length × Width.

Width = 3

Thus, the area is 3 × L

3× (4.75) ≤ 3×L ≤3× (5.25)

14.25 ≤ 3×L ≤ 15.75

So the minimum area is 14.25 cm^2

The maximum area is 15.75 cm^2
