Answer:
D: 14q + 21√qr
Step-by-step explanation:
We want to find the product of;
(2√q + 3√r) and 7√q.
Where p and q are integers.
Using distributive property, we have;
(2√q × 7√q) + (3√r × 7√q)
>> 14q + 21√qr
Correct option is D

Answer:
<em><u>x = -6</u></em>
Step-by-step explanation:
7 = -2x - 5
12 = -2x
x = -6
The whole triangle and the triangle with the angle K are both isosceles triangle which means two angles are equal.
The total triangle angle is 180. Using this you can find the K.
The solution to the system of linear equations is (-1,3). Here's how I got my answer step by step using the substitution method.
Step 1: Solve for either x or y in one of the two equations.
y - 4x = 7
+ 4x + 4x
-----------------------
y = 4x + 7
Step 2: Plug in the value that you got for x or y into the equation that you haven't worked with yet.
2(4x + 7) + 4x = 2
8x + 14 + 4x = 2
12x + 14 = 2
- 14 - 14
-----------------------
12x = -12
------- -------
12 12
x = -1
Step 3: Plug in the number you got for y or x into either of the two equations.
y - 4(-1) = 7
y + 4 = 7
- 4 - 4
-------------------
y = 3
The final answer is (-1,3). If you want to check to make sure that this coordinate is a solution to the system of equations, all you have to do is plug in -1 for x and 3 for y into both equations.
Equation 1: y - 4x = 7
Equation 2: 2y + 4x = 2
3 - 4(-1) = 7 2(3) + 4(-1) = 2
3 + 4 = 7 6 - 4 = 2
7 = 7 2 = 2
I hope all of this makes sense to you :)
