It's not clear where point Y is located. If Y is the midpoint, and Y is on line XZ, then we can say that XY = 25 and YZ = 25 (since Y cuts XZ in half; the two equal portions are XY and YZ)

I'm using the segment addition postulate XY+YZ = XZ

However, all of this is based on the assumption that Y is the midpoint and on line XZ.

16x^2 - 49 when factored is ?
vaieri [72.5K]

Answer:

(4x-7)(4x+7)

Step-by-step explanation:

This is called the Difference of Two Squares (DOTS).

These are the conditions that must be met for DOTS to work:

•There must be 2 terms.

•They must be separated by a negative sign.

•Each term must be a perfect square.

First, you have to find 2 square numbers that times together to make 16.

4×4=16

As we want 16x², you just need to make the 4 become 4x:

4x times 4x equals 16x²

Then, find 2 squares that times together to make 49.

7×7=49

You can put the two squares into a bracket with the x variable first, then the number:

(4x-7)(4x+7)

In the brackets, you always put the negative sign in the first one and then the plus sign in the second one.

You can double check your answer by expanding it back out again using FOIL:

F-First

O-Outer

I-Inner

L-Last

Times the First two in the two brackets:

4x times 4x equals 16x²

Times the Outer two:

4x times 7 equals 28x

Times the Inner two:

-7 times 4x equals -28x

Times the Last two:

-7 times 7 equals -49

Form an equation:

16x²+28x-28x-49

The 28x cancel out to leave:

16x²-49

Hope this helps :)

Choose the correct simplification of the expression (a^4/b^2)^3
Oksanka [162]
The answer is B: <span> a^12/b^6

Proof:

Simplify the following:
(a^4/b^2)^3

Multiply each exponent in a^4/b^2 by 3:
(a^(3×4))/((b^2)^3)

3×4 = 12:
a^12/(b^2)^3

Multiply exponents. (b^2)^3 = b^(2×3):
a^12/b^(2×3)
2×3 = 6:
Answer:  a^12/b^6</span>

A right pyramid with a square base has a base length of x inches, and the height is two inches longer than the length of the bas
vredina [299]

Answer:

The answer to your question is Volume = (1/3)(x²)(x + 2)

Step-by-step explanation:

Data

length = x

height = x + 2

Volume = ?

Formula

Volume = 1/3Ab h

Process

1.- Calculate Ab

Ab = length x length

-Substitution

     = (x)(x)

-Simplification

     = x²

2.- Substitution

Volume = (1/3)(x²)(x + 2) or (1/3)(x³ + 2x²)
