Answer:
(x+11)(x-11)
Step-by-step explanation:
Rewrite 121 as 11².
11²-x²
Since both terms are perfect squares, factor using the differences of squares formula, a²-b²=(a+b)(a-b) where a=11 and b=x.
(11+x)(11-x)

This is the same as writing 7d^2
==================================================
Explanation:
When we add a number to itself repeatedly, we can use multiplication to shorten things. For example: 3+3+3+3 = 5*3 = 15. We have five copies of '3' being added, which explains the 5 times 3.
Extending this idea leads us to shortening repeated multiplications into exponentiations. In the case of [tex]7*d*d[/tex], we have two copies of 'd' being multiplied. We replace [tex]d*d[/tex] with [tex]d^2[/tex] which is the same as d^2. The ^ symbol means "exponent".
The exponent (2) tells us how many copies of the base (the term d) we multiply out.
Another example would be [tex]d^3 = d*d*d[/tex]
So that's why [tex]7*d*d = 7d^2[/tex]

the angle of elevation from the bottom of the lift to the top of Snowbowl mountain is 33 degrees. If the height of the mountain is 544 meters, what is the length of a list from the bottom of a mountain to the top?
Answer:
Step-by-step explanation:
[tex]tan33=544/x\\ \\ x=\frac{544}{tan33}m\\ \\ x\approx 837.7m[/tex]
9514 1404 393
Answer:
999 meters
Step-by-step explanation:
The length of the lift line represents the hypotenuse of a right triangle. The side opposite the given angle is the height of the mountain. The applicable trig relation is ...
Sin = Opposite/Hypotenuse
We want to find the hypotenuse, so we use the rearranged form ...
hypotenuse = (mountain height)/sin(33°)
lift length = (544 m)/sin(33°) ≈ 998.83 m
The length of the lift from bottom to top is about 999 meters.

What is the difference between 4/5- 1/2 *
Answer:
0.3
Step-by-step explanation:
Answer:
3/10
Step-by-step explanation:
1. find the lowest common denominator which is 10.
2. for 4/5 you have to multiply 5 by 2 in order to get 10, so you multiply the numerator by 2 as well which gives you 8/10.
3. for 1/2 you have to multiply 2 by 5 in order to get 10, so you multiply the numerator by 5 also which gives you 5/10
4. you work out the difference between both numerators which is 3 and keep the denominator the same

Here is a true statement: -6.7 < -6.2. Select all of the statements that are equivalent to -6.7 < -6.2.
Group of answer choices
-6.7 is further to the right on the number line than -6.2.
-6.2 is further to the left on the number line than -6.7.
-6.2 is less than -6.7.
-6.2 is greater than -6.7.
-6.7 is less than -6.2.
-6.7 is greater than -6.2.
=============================================================
Explanation:
Let's go through the answer choices one by one to see which are true and which are false.
A) This is false because -6.7 is to the left of -6.2 on the number line.B) This is false for similar reasoning as choice A.C) This is false because -6.7 < -6.2 means that -6.7 is the smaller value.D) This is true. The value -6.2 is larger than -6.7; we can say that -6.7 < -6.2 is the same as -6.2 > -6.7 (note the two sides swap places and the inequality sign flips).E) This is true and it's directly from -6.7 < -6.2; the inequality sign has the pointed edge aimed at the smaller value, while the non-pointed side is aimed at the larger value. You can think of an alligator's mouth that represents the < sign. The alligator will eat the larger value each time, so this is where the mouth faces.F) This is false since it contradicts choice E above. I recommend drawing out a number line to help see why -6.7 < -6.2 is a true statement.which of these equations could represent the blue line?
