If a = (x-3) and b = (x+3), show that 2ab = 2x square - 18
Step-by-step explanation:
ab = (x - 3)(x + 3)
multiply
ab = x² + 3x - 3x - 9
Simplify
ab = x² - 9
---------------------------
2ab = 2(x² - 9)
Distribute
2ab = 2x² - 18

The region bounded by y=x^2+1, y=x, x=-1, x=2 with square cross sections perpendicular to the x-axis.
Answer:
The bounded area is 5 + 5/6 square units. (or 35/6 square units)
Step-by-step explanation:
Suppose we want to find the area bounded by two functions f(x) and g(x) in a given interval (x1, x2)
Such that f(x) > g(x) in the given interval.
This area then can be calculated as the integral between x1 and x2 for f(x) - g(x).
We want to find the area bounded by:
f(x) = y = x^2 + 1
g(x) = y = x
x = -1
x = 2
To find this area, we need to f(x) - g(x) between x = -1 and x = 2
This is:
[tex]\int\limits^2_{-1} {(f(x) - g(x))} \, dx[/tex]
[tex]\int\limits^2_{-1} {(x^2 + 1 - x)} \, dx[/tex]
We know that:
[tex]\int\limits^{}_{} {x} \, dx = \frac{x^2}{2}[/tex]
[tex]\int\limits^{}_{} {1} \, dx = x[/tex]
[tex]\int\limits^{}_{} {x^2} \, dx = \frac{x^3}{3}[/tex]
Then our integral is:
[tex]\int\limits^2_{-1} {(x^2 + 1 - x)} \, dx = (\frac{2^3}{2} + 2 - \frac{2^2}{2}) - (\frac{(-1)^3}{3} + (-1) - \frac{(-1)^2}{2} )[/tex]
The right side is equal to:
[tex](4 + 2 - 2) - ( -1/3 - 1 - 1/2) = 4 + 1/3 + 1 + 1/2 = 5 + 2/6 + 3/6 = 5 + 5/6[/tex]
The bounded area is 5 + 5/6 square units.
A coin will be flipped three times. The result of each flip is either heads (H) or tails (T). The outcome HTH represents the first result is heads, the
second result is tails, and the third result is heads. The list of all possible outcomes is shown. Each outcome is equally likely.
HHH, HHT, HTH, HTT, THH, THT, TTH, TTT
If the result of the first flip is tails, what is the probability that the coin lands on heads two times?
Answer: A. 1/4
Step-by-step explanation:
1/2 x 1/2= 1/4
since tails is the first one that landed, the probability for the other two to be heads is 1/4

Find the hypotenuse of a right triangle if the legs are 22 and 26. Round to nearest hundredth
Answer:
Step-by-step explanation:
length of Legs of the right angle triangle = 22 (unit) and 26 (unit)
To find the length of hypotenuse of the right angle triangle, we have to use Pythagoras property
Lets keep hypotenuse as "h" and one leg as "a" and another as "b"
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]h^{2}[/tex]
[tex]22^{2}[/tex] + [tex]26^{2}[/tex] = [tex]h^{2}[/tex]
484 + 676 = [tex]h^{2}[/tex]
[tex]h^{2}[/tex] = 1,160
h = [tex]\sqrt{1,160}[/tex]
h = 34.05 (unit)

The number 44 is multiplied by a 44-digit number that contains only ones. What is the sum of the digits of the product?
Answer:
352.
Step-by-step explanation:
The product will have 45 digits, the fisrt and last digit will be 4 and the middle 43 will be 8.
So the sum = 2*4 + 43*8
= 352.

Homemade applesauce is one of Duncan's favorite foods, so he bought 10 pounds of apples at the farmers' market. His applesauce recipe says that 8 ounces of apples make 1 cup of applesauce. How many cups of applesauce can he make with 10 pounds of apples?
Answer:
20 cups of applesauce
Step-by-step explanation:
8 ounces = 0.5 pounds
Pounds of apples : cups of applesauce
0.5 pounds : 1 cup = 10 pounds : x cups
0.5/1 = 10/x
0.5*x = 1*10
0.5x = 10
x = 10/0.5
x = 20 cups of applesauce
10 pounds of apples will make 20 cups of applesauce

A student needs 15 minutes to solve an algebra problem. How many minutes does the student need to solve 5 problems?
it's easy, you only need to divide 15 by 5.
Like this :
15÷5= 3
• because 5×3 = 15 , so you just need to flip it over
so, the student need 3 minutes to solve 5 problems

Answer:
z = 113
y = 31
Step-by-step explanation:
j || n and line a is their transversal. (given)
Therefore,
z° = 180° - 67° (exterior angles on the same side of transversal)
z°= 113°
z = 113
(5y - 88)° = 67° (exterior alternate angles)
5y - 88 = 67
5y = 67 + 88
5y = 155
y = 155/5
y = 31

What 2 sides need to be congruent in order to prove the 2 triangles are congruent by HL?
PLEASE HELP ASAP!
Answer:
The two hypotenuses.
Step-by-step explanation:
HL or Hypotenuse-Leg Theorem: two right triangles are congruent if and only if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of the other right triangle.
Since we already know the bottom leg of each triangle is congruent, we only need to know the two hypotenuses.

please help me answer this question-
Answer:
[tex] \displaystyle GH = 2 \sqrt{30} [/tex]
[tex] \displaystyle FH = 2 \sqrt{10} [/tex]
[tex] \displaystyle m \angle G = {30}^{ \circ} [/tex]
Step-by-step explanation:
QUESTION-2:we are given a right angle triangle
it's a 30-60-90 triangle of which FH is the shortest side
remember that,in case of 30-60-90 triangle the the longest side is twice as much as the shortest side thus
our equation is
[tex] \displaystyle 2FH=4\sqrt{10}[/tex]
divide both sides by 2
[tex] \displaystyle\frac{2FH}{2}= \frac{ 4 \sqrt{10} }{2}[/tex]
[tex] \displaystyle FH =2 \sqrt{10}[/tex]
Question-1:in order to figure out GH we can use Trigonometry because the given triangle is a right angle triangle
as we want to figure out GH we'll use sin function
remember that,
[tex] \displaystyle \sin( \theta) = \frac{opp}{hypo} [/tex]
let our opp, hypo and [tex]\theta[/tex] be GH, 4√10 and 60° respectively
thus substitute:
[tex] \displaystyle \sin( {60}^{ \circ} ) = \frac{GH}{4 \sqrt{10} } [/tex]
recall unit circle:
[tex] \displaystyle \frac{ \sqrt{3} }{2} = \frac{GH}{4 \sqrt{10} } [/tex]
cross multiplication:
[tex] \displaystyle 2 GH = 4 \sqrt{10} \times \sqrt{3} [/tex]
simplify multiplication:
[tex] \displaystyle 2 GH = 4 \sqrt{30} [/tex]
divide both sides by 2:
[tex] \displaystyle GH = 2 \sqrt{30} [/tex]
QUESTION-3:Recall that, the sum of the interior angles of a triangle is 180°
therefore,
[tex] \displaystyle m \angle G + {60}^{ \circ} + {90}^{ \circ} = {180}^{ \circ} [/tex]
simplify addition:
[tex] \displaystyle m \angle G + {150}^{ \circ} = {180}^{ \circ} [/tex]
cancel 150° from both sides
[tex] \displaystyle m \angle G = {30}^{ \circ} [/tex]
Find the value of x in the triangle shown below

What is the radius of the circle?
Answer:
8×ED=3×15

[tex] \frac{ae}{be} = \frac{ce}{de} = \frac{bc - be}{ad - ae} \\ \\ = > \frac{8}{3} = \frac{15 - 3}{ad - 8} \\ \\ < = > \frac{8}{3} = \frac{12}{ad - 8} \\ \\ = > ad - 8 = \frac{12 \times 3}{8} = 4.5 \\ \\ < = > ad = 4.5 + 8 = 12.5 \\ \\ = > r = 12.5 \div 2 = 6.25[/tex]
