Answer:
1 apple
Step-by-step explanation:
4(2x + 3) = 2(3x - 4)
8x + 12 = 6x - 8
8x - 6x = -8 - 12
2x = - 20
x = -20/2
x = -10......if u get a variable equal to a number, then there is 1 solution
if u would have ended up with 0 = 0 or 5 = 5...or something that is equal, then there would be infinite solutions.
if u would have ended up with 2 = 3, or 5 = 7...or something unequal, then there would have been no solution.
Answer:
D. 10.2
Step-by-step explanation:
Since the triangle is a right triangle we can use the Pythagorean theorem.
I will call the hypotenuse
, so in this case:
![h=19](https://tex.z-dn.net/?f=h%3D19)
and one leg will be
, in this case:
![l=16](https://tex.z-dn.net/?f=l%3D16)
and the unknown for this problem is the other leg which in the image is called
.
So the formula for the Pythagorean theorem:
![h^2=l^2+x^2](https://tex.z-dn.net/?f=h%5E2%3Dl%5E2%2Bx%5E2)
clearing for x:
![x^2=h^2-l^2\\x=\sqrt{h^2-l^2}](https://tex.z-dn.net/?f=x%5E2%3Dh%5E2-l%5E2%5C%5Cx%3D%5Csqrt%7Bh%5E2-l%5E2%7D)
substituting
and
:
![x=\sqrt{19^2-16^2}\\ x=\sqrt{361-256}\\ x=\sqrt{105}\\ x=10.2](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B19%5E2-16%5E2%7D%5C%5C%20x%3D%5Csqrt%7B361-256%7D%5C%5C%20x%3D%5Csqrt%7B105%7D%5C%5C%20x%3D10.2)
the value of x is option D. 10.2
