Yall what is 10+9x please help thanks shawty
Answer:
19x I believe
Step-by-step explanation:
Added 10 and 9, left the x
Answer:
10+9x can't be combined to make a number
Step-by-step explanation:
This is because the 10 doesn't have the variable x so we can't combine them together
If the 10 had an x beside it, it would've become 19x, but it doesn't so it stays as is
Sorry if this is incorrect!!!!!

Please solve; x³+y³+z³=k
Answer:
It's called a Diophantine Equation, and it's sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. One answer is x = 1, y = -1, and z = 2.

A cylinder has a height of 13 feet and a radius of 11 feet. What is its volume? Use a ~ 3.14
and round your answer to the nearest hundredth.
Answer:
4939.22 feet cubed.
Step-by-step explanation:
The formula for the volume of a cylinder is V=3.14*r^2*h
First we square the raidus, which is 11 in this problem. 11 squared is 121.
Next we multiply everything together.
3.14*121 is 379.94. Then, 379.94 * the height, which is 13, is 4939.22.
Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22
If you place a 34-foot ladder against the top of a building and the bottom of the ladder is 25 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answer:
23.0 ft to nearest 1./0.
Step-by-step explanation:
By Pythagoras:
34^2 = h^2 + 25^2 where h = the height of the building
h^2 = 34^2 - 25^2 = 531
h = 23.04 ft.
which of the following are zeros in the equation x (x - 3)(x + 6)(x - 7) = 0
Answer:
The given polynomial x(x -3)(x +6)(x -7)= 0 is of degree 4. Therefore, it has 4 zeros as follows. So, x = 3 is the second zero. So, x = -6 is the third zero.

15×4=60
3×3=9
9×2=18
60+18=78
What is the surface area of the figure? Use 3.14 for π.
847.8 cm 2
2,402.1 cm 2
3,108.6 cm 2
12,717 cm 2
Answer:
Option 3
Step-by-step explanation:
We want to work out the surface-area
This is a cylinder and the formula for the surface area of a cylinder is :
2πrh+2πr^2
^ means to the power of
The radius is 15
The length is 18
2(3.14)(15)(18) + 2(3.14){15}^2
Part 1:
(6.28)(15)(18)
(6.28)(270)
1695.6
Part 2:
First, we do the exponents,
15^2 = 225
(6.28)(225)
1413
Part 3:
1695.6 + 1413 = 3108.6
Answer: 3108.6

The area of a circle is 111.6 square centimeters. What is a diameter? Use 4.1 for ℼ. PLEASEEEE HURRYYY
Answer:
Step-by-step explanation:
Area is + 111.6 square meters
Formula : A/ 3.14 / 2
111.6 / 3.14 = 35.54
35.54 is the radius so multiply by 2 to get diameter .
35.54 / 2 = 17.77
Hope that’s right:)

What is the value of x and the measure of ∠DBC, respectively?
A. x = 3; ∠DBC = 9
B. x = 36; ∠DBC = 108
C. x = 18; ∠DBC = 36
D. x = 18; ∠DBC = 54
Answer:
Hmm i don't know is A B C D
CBA should be hmm 90 degrees I think
Then you should be able to calculate
it's so easy
Step-by-step explanation:
Answer:
D. x = 18; ∠DBC = 54
Step-by-step explanation:
m∠ABD + m∠CBD = 90°
2x + 3x = 90°
5x = 90°
x = 18°
m∠DBC = 3x
m∠DBC = 3(18°)
m∠DMC = 54°

Answer: 12.9
Step-by-step explanation:
lThe area of the triangles is 3/2 x 2.6 = 3.9/2 = 1.95. since there is 2 triangle do 1.95 x 2 = 3.9. and the area of the square is 3x3 = 9. All in all, 3.9 + 9 = 12.9.

Everytime your X goes up by 1, your Y goes up by 4
making the space between 6 and 14 = 10
the exponential factor equation would look something like this
g(x)=3^x
meaning every time x goes up by 1, your exponential factor gets multiplied by 3, making 14y have an exponential factor of 1.

Answer:
Let x = # of hours Sophia spends ironing shirts
Let y = # of hours London spends ironing shirts
Equations: x + y = 11 and 40x + 25y= 365
Step-by-step explanation:
If Sophia and London worked a combined 11 hours, then one of our equations is : x + y = 11
They also note that Sophia and London both ironed 365 shirts, and Sophia irons 40 shirts per hour while London can iron 25 shirts per hour. Our next equation is : 40x + 25y= 365
