Given QR is congrent to LN and QR = 4x + 2 and LN = x + 7.
So, QR = LN
Hence, we can set up an equation as following:
4x + 2 = x + 7
4x + 2 - x = x + 7 - x Subtract x from each sides.
3x + 2 = 7 By simplifying.
3x + 2 - 2 = 7 - 2 Subtract 2 from each sides.
3x = 5
Divide each sides by 3 to isolate x.
So, 
Next step is to plug in in QR = 4x+2 to get length of QR.
So, 
Since 2 can be written as 2/1.
By multiplying the second fraction by the common denominator 3.
By simplifying the second fraction.
So, 
Answer:
16 m^2
Step-by-step explanation:
Area of triangle = (Base * Height) / 2
Area of triangle = ( 8 * 4 ) / 2
Area of triangle = 16
If it's not 6 cubic feet (because by the wording the answer is given).
If one dimension of the amount of soil they remove is 6, then you have to do 6*6*6= 216
If the total amount of soil removed is 6 cubic feet, then the dimensions of the cube would be ![\sqrt[3]{6}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6%7D)
There is no least common factor between 19 and 17, so the question itself is the answer. (Answer is 19:17)
