Answer:

First you subtract 10 from both sides of the equation. The new equation has the same meaning. Then multiply both sides by 3. The result gives the value of x explicitly. You check by plugging that value into the original equation, and evaluate to get 14=14.

Answer:

d = 12

Step-by-step explanation:

Isolate the term with d by subtracting 10 from both sides of the equation

\frac{d}{3} = 4 ( multiply both sides by 3 )

d = 12

Find the missing side.<br> 6 is A^2 <br>10 is B^2<br> what is the missing side​
topjm [15]

Answer:

8

Step-by-step explanation:

This is a right triangle, which fits the Pythagorean Theorem, a^2 +b^2 = c^2. The variables a, b, and c all are sides of the triangle, while a and b are the two legs and c is the hypothenuse.

In this problem, we see that 6 and x are the legs and 10 is the hypothenuse.    We put 6 as "a" and x as "b" (but it doesn't matter which is a and b) and 10 is c. Therefore, we have the equation:

6^2 + x^2 = 10^2

which further simplifies to:

36 + x^2 = 100

x^2 = 64

and so x would equal 8 (or -8, but it is impossible to have a side length of -8).

Therefore, the missing side is 8.

Use the given information to determine if the geometric series converges or
lana66690 [7]

Answer:

c) The series diverges. There is no sum.

Step-by-step explanation:

A geometric series is a series of the form:

S = \Sigma_{i=0}^{n} a\cdot r^{i}, \forall i \in \mathbb{N}_{O}

Where:

a - First term of the series, dimensionless.

r - Common ratio, dimensionless.

A geometric series converges only if |r| < 1. As r > 1, the geometric series diverges. Hence, the right answer is C.

The length of a rectangle picture frame is 2 centimeters more than twice it’s width. If the area of the frame is 364 square cent
sergeinik [125]

Answer:

Length:28 cm

Width: 13 cm

Step-by-step explanation:

Let

x ---> the length of a rectangle picture frame

y ---> the width of a rectangle picture frame

we know that

The area of a rectangle picture frame is equal to

A=xy

we have

A=364\ cm^2

so

364=xy ----> equation A

The length of a rectangle picture frame is 2 centimeters more than twice it’s width

so

x=2y+2 ---> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (28,13)

see the attached figure

therefore

Length:28 cm

Width: 13 cm
