Solve for the value of x in the diagram: Show your work and explain the steps you used to solve.

Answers

Answer 1

Answer:

Since EB is parallel to CD, triangles ABE and ACD are similar. So, we can set up a proportion between correspondent sides:

$AE/ AD = AB / AC$

Substituting values, we have

$16/ 40=35-x/ 35$

This implies

$40(35-x)=560 \iff 1400-40x=560 \iff 40x=840 \iff x=21$

If the complex number x = 3 + bi and |x|^2 = 13, which is a possible value of b? A. 2
B. 3
C. 9
D. 10

20 points to the brainliest user!!!!

Answers

If x=3+bi, then

$|x|=√(3^2+b^2).$

You know that $|x|^2=13,$ then

$\left(√(3^2+b^2)\right)^2=13,\n \n 9+b^2=13,\n \nb^2=4,\n \nb=\pm 2.$

Two possible complex numbers satisfy these conditions:

$x_1=3+2i, \ x_2=3-2i.$

As you can see the possible value of b is 2.

Answer: correct choice is A.

What is the correct answer to 7^2

Answers

Answer:

Step By Step Explanation:

1. Take the number 7.

2. Multiply it by itself: $7 \times 7$.

3. The result is 49.

The "^" symbol is an exponent, which tells you how many times to multiply the base number (in this case, 7) by itself. Since the exponent is 2, you multiply 7 by itself once to get 49.

Answer: 49

Exponentiation is equal to repeative multiplication. If exponent is 2, you multiply number in the basis.

So for

So the answer is 49
