What is 100x^2 - 64y^2 =

Mathematics
1 answer:
fredd [130]3 years ago
3 0

Answer:

(10x + 8y)(10x - 8y)

Step-by-step explanation:

The given expression is 100x^2 -64y^2

100 can be written as 10^2

64 can be written as 8^2

100x^2 - 64y^2  = (10x)^2 - (8y)^2

We know that a^2 - b^2 = (a +b )(a - b)

Applying the formula, we get

(10x)^2 - (8y)^2 = (10x + 8y)(10x - 8y)

Answer: (10x + 8y)(10x - 8y)

Thank you.

Help me find the slope
shusha [124]

Answer:

-3/2

Step-by-step explanation:

Slope is defined as \frac{rise}{run},

So the line goes down 6 instead of rising, making the rise negative: -6

The line goes over 4, making the run: 4

So -6/4 or -3/2
