Mathematics
1 answer:
lora16 [44]3 years ago
3 0

Answer:

(11b^2 + 7) (11b^2 - 7)

Explanation:

Since both terms are perfect squares, factor using the difference of squares formula,  a^2 - b^2 = (a + b) (a - b) where a = 121b^4 and b = 49

Olenka [21]

Answer:

The answer to your question is:

Step-by-step explanation:

   \frac{x^{2}-16 }{2x + 4} \frac{x^{3}-2x^{2} + x }{x^{2}+ 3x - 4}

Factorize    \frac{(x+4)(x-4)}{2(x+2)}  \frac{x(x^{2}-2x + 1) }{(x+4)(x-1)}

Factorize    \frac{(x+4)(x-4)}{2(x+2)} \frac{x(x-1)^{2} }{(x+4)(x-1)}

Simplify      \frac{x(x-4)}{2(x+2)}

HELPPPPPPPPPP PLEASE WILL MARK BRAINLIEST!!!!!!!! Assuming that a soap bubble is a perfect sphere, what is the diameter of a bub
9966 [12]

Answer: 12.4 cm

Step-by-step explanation:

Since we are given the volums, we can work our way backwards to solve for radius, and then for diameter.

V=\frac{4}{3} \pi r^3

1000=\frac{4}{3} \pi r^3

750=\pi r^3

r^3=238.7324146

r=6.2

Now that we have r, we multiply it by 2 to get diameter.

2×6.2=12.4

If s(x) = x - 7 and t(x) = 4x2 – x + 3, which expression is equivalent to<br> to (t•s )(x)?
serg [7]

Answer:

(t•s )(x) = 4x^3 - 29x^2 + 10x - 21

Step-by-step explanation:

(t•s )(x) is the product of functions s and t:

(t•s )(x) = ( 4x^2 - x + 3)(x - 7).  Applying the Distributive Property of Multiplication, we get:

(t•s )(x) = 4x^3 - 28x^2 - x^2 + 7x + 3x - 21

which needs to be simplified by combining like terms:

(t•s )(x) = 4x^3 - 29x^2 + 10x - 21
