What is the factorization of 121b^4 − 49?

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

Erick, Mia, and Isabelle golfed 9 holes. Erick scored 10 more than Mia, and Isabelle scored 16 less than twice Mia's score. Use
Rama09 [41]
Let Mia's score be x.  Then, Erick scored 10 more than Mia, so his score is x+10.  Isabelle scored 16 less than twice Mia's score, so her score is 2x-16.  We can see that x + x + 10 + 2x - 16 is the sum of these variables, so the expression represents the total of their scores in this scenario.  Moreover, we recall that the variable in the expression, x, represents Mia's score.

To simplify this expression, we add up the variables and the numbers separately, giving us x+x+10+2x-16 = (x+x+2x) + (10-16) = 4x-6.  Therefore, in simplified form, the expression is equal to 4x - 6.  The constant term in an expression is the term not multiplied by a variable, so in this case, it is -6.

Going into the final exam, which will count as two tests, Brooke has test scores of 75, 82, 70, 65, and 90. What score does Broo
dusya [7]
Brooke needs to get a 98 on the final to get an average of 80.
So you know that the total of the five given score is 382 by adding all the scores.
Now you multiply the average, 80 by 6 for the total of six tests including the final which is 480
Then you subtract 480-382 to find your answer.

Escribe el nombre de algún tipo de ángulo que se forma "Entre Dos rectas Paralelas y una Secante"
blsea [12.9K]

Answer:

We see that opposite angles are two angles between two secant lines (“secant lines” simply means two lines that cross each other) that share a vertex (that is why they are called “vertical” angles). We see also that they are not adjacent (which means next to each other) but opposite each other.

Step-by-step explanation:

Vemos que los ángulos opuestos son dos ángulos entre dos líneas secantes (“líneas secantes” simplemente significa dos líneas que se cruzan) que comparten un vértice (por eso se llaman ángulos “verticales”). También vemos que no son adyacentes (lo que significa uno al lado del otro) sino uno frente al otro.
