Find the sum of 4\sqrt{5}4 5 and 3\sqrt{2}3 2 in simplest form. Also, determine whether the result is rational or irrational and explain your answer. Result: The result is because it be written as the ratio of two integers and its decimal expansion terminate or repeat.
Answer:
I would guess irrational, but Can you post a pic?
Step-by-step explanation:
The result of 4√5 + 3√2 is an irrational number because it contains the irrational term 7√5, which cannot be written as the ratio of two integers and does not have a terminating or repeating decimal expansion.
What is a rational number?A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.
The number is given in the question as follows:
4√5 and 3√2
We have to determine the sum of 4√5 and 3√2.
To find the sum of 4√5 and 3√2 , we can simply add the two terms:
⇒ 4√5 + 3√2
⇒ (4 + 3)√5 + 0√2
⇒ 7√5
In conclusion, the result of 4√5 + 3√2 is an irrational number because it contains the irrational term 7√5, which cannot be written as the ratio of two integers and does not have a terminating or repeating decimal expansion.

how many solutions does 3(4+x)=7x-2(2x+3) have
Answer: no solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
3(4+x)=7x−2(2x+3)
Step 1: Simplify both sides of the equation.
3(4+x)=7x−2(2x+3)
(3)(4)+(3)(x)=7x+(−2)(2x)+(−2)(3)(Distribute)
12+3x=7x+−4x+−6
3x+12=(7x+−4x)+(−6)(Combine Like Terms)
3x+12=3x+−6
3x+12=3x−6
Step 2: Subtract 3x from both sides.
3x+12−3x=3x−6−3x
12=−6
Step 3: Subtract 12 from both sides.
12−12=−6−12
0=-18
Quadrilateral ABCD is shown below. Find the value of x
What’s the volume of the figure?
Answer:
4,050 ft^3
Step-by-step explanation:
Separate the figure into a cube and a square pyramid.
Volume of the cube (a^3):
15 x 15 x 15 = 3,375
3,375 ft^3
Volume of the square pyramid (lwh/3):
15 x 15 x 9/3 = 675
675 ft^3
Add the volumes of both figures:
675 ft^3 + 3,375 ft^3 = 4,050
The volume of the whole figure is 4,050 cubic feet.
Hope this helps!

Solving the equation algebraically (show mathematical thinking)
251 = c - 811
Check Required
helppp
Answer:
c = 1062
Step-by-step explanation:
first move the terms
251 - c = -811
move the constant to the right hand side and change its sign
-c = -811 - 251
calculate the difference
- c = -1062
change the signs in both sides of the equation
c = 1062
Answer:
1062
Step-by-step explanation:
811 + 251=1062
The highest temperature on a winter day in New York City was 11°C. The lowest temperature on the same day in the same city was -8 °C. How much did the temperature drop over the course of the day?
Answer:
29°C
Step-by-step explanation:
Given the following
Highest temperature= 11°C
lowest temperature
Drop in temperature = highest - lowest
Drop in temperature = 18 - ()-11)
Drop in temperature = 18 + 11
Drop in temperature = 29°C

Solve this linear equation for p.
2.6(5.5p – 12.4) = 127.92
1. Distributive property: 14.3p − 32.24 = 127.92
2. Addition property of equality: 14.3p − 32.24 + 32.24 = 127.92 + 32.24

Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two
sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 9 cm
Answer:
8 cm , 9cm
Step-by-step explanation:
sum of any two sides >third side
difference of any two sides<third side
only 8 cm and 9 cm satisfies it
8+9=17>13
9-8=1<13
What is the measure of arc XY in the diagram below?
Answer:
30 = XY
Step-by-step explanation:
Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)
41 = 1/2 ( 112 - XY)
Multiply each side by 2
2*41 = 2* 1/2 ( 112 - XY)
82 = 112 - XY
Subtract 112 from each side
82 - 112 = -XY
-30 = -XY
Multiply by -1
30 = XY

please help i dont understand
Answer:
40 degrees
Step-by-step explanation:
using 180 minus 94 we can find the inner left angle of the triangle as 86 degrees and using 86 plus 54 we get 140. 180 minus 140 for the last angle F so 40 degrees
What is the slope and y-intercept of the graph of -x + 2y = 6?
-1/2, 1
1, 6
1, 3
1/2, 3
Answer:
1/2, 3
Step-by-step explanation:
Rearrange the equation into y = mx + b form, where m is the slope and b is the y intercept:
-x + 2y = 6
2y = x + 6
y = 1/2x + 3
So, 1/2 is the slope and 3 is the y intercept.
The correct answer is 1/2, 3

Solve for P.
-1 + 14 p = -435
Answer:
P = -31
Step-by-step explanation:
-1 + 14p = -435
Remove the -1 by adding it from both sides.
14p = -434
Remove the 14 by dividing it from both sides.
p = -434/14
p = -31
Answer:
-31
Step-by-step explanation:
-1+14p=-435
14p=-435-(-1)
14p=-435+1
14p=-434
p=-434/14
p=-31
Find the volume of the sphere. Round your answer to the nearest tenth. Radius is 12ft
Answer: 7238.2[tex]ft^3[/tex]
Step-by-step explanation:
The formula for a sphere's volume is [tex]V=\frac{4}{3} \pi r^3[/tex].
Substitute r = 12 in the formula: [tex]V=\frac{4}{3} \pi (12)^3[/tex]
Then calculate (type the right side of the equation above in your calculator), and you will get an answer of 2304π. When you simplify further, you get 7238.22947. Rounded to the nearest tenth, it is 7238.2.
∴, the volume of the sphere is 7238.2[tex]ft^3[/tex], to the nearest tenth.
*note: it's [tex]ft^3[/tex] (feet cubed) because a sphere is a 3D object, so its volume is also a 3D measurement.
Find x pls I'm preparing for a test ;-;
Answer:
x = 5
Step-by-step explanation:
13^2 - 12 ^2 = x^2
169 - 144 = x^2
25 = x^2
[tex]\sqrt{25} = \sqrt{x^2}[/tex]
x = 5
Answer:
x = 5
Step-by-step explanation:
12² + x² = 13²
144 + x² = 169
144 - 144 + x² = 169 - 144
x² = 25
√x² = √25
x = 5
