Answer:
Step-by-step explanation:
in complementary angles sum of two angles is always 90 degree .
2x+18+6x-8=90
8x+10=90
8x=90-10
x=80/8
x=10
angle B=6x-8
=6*10-8
=60-8
=52 degree
therefore angle B is 52 degree
Answer:
![7\sqrt[3]{x^2}](https://tex.z-dn.net/?f=7%5Csqrt%5B3%5D%7Bx%5E2%7D)
Step-by-step explanation:
The rule of exponents that dictates this to be solved is:
![x^{\frac{a}{b}}=\sqrt[b]{x^a}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Csqrt%5Bb%5D%7Bx%5Ea%7D)
The power of 2/3 is on "x", NOT 7, so we use this property to write it as:
![x^{\frac{a}{b}}=\sqrt[b]{x^a} \\7x^{\frac{2}{3}}=7\sqrt[3]{x^2}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Csqrt%5Bb%5D%7Bx%5Ea%7D%20%5C%5C7x%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D7%5Csqrt%5B3%5D%7Bx%5E2%7D)
third answer choice is right, ![7\sqrt[3]{x^2}](https://tex.z-dn.net/?f=7%5Csqrt%5B3%5D%7Bx%5E2%7D)

Answer:
Step-by-step explanation:
Given
Box has top and bottom as square
![Volume =7 m^3](https://tex.z-dn.net/?f=Volume%20%3D7%20m%5E3%20)
let l ,b ,h be length, breadth and height of box
l=b because top and bottom as square
thus ![volume =b^2\cdot h](https://tex.z-dn.net/?f=volume%20%3Db%5E2%5Ccdot%20h)
![b^2=\frac{7}{h}](https://tex.z-dn.net/?f=b%5E2%3D%5Cfrac%7B7%7D%7Bh%7D)
Total surface area![(TSA)=2\left ( lb+bh+hl\right )](https://tex.z-dn.net/?f=%28TSA%29%3D2%5Cleft%20%28%20lb%2Bbh%2Bhl%5Cright%20%29)
![TSA=2\left ( b^2+bh+bh\right )](https://tex.z-dn.net/?f=TSA%3D2%5Cleft%20%28%20b%5E2%2Bbh%2Bbh%5Cright%20%29)
![TSA=2\left ( b^2+2bh\right )](https://tex.z-dn.net/?f=TSA%3D2%5Cleft%20%28%20%20b%5E2%2B2bh%5Cright%20%29)
![TSA=2\left ( \frac{7}{h}+2h\times \sqrt{\frac{7}{h}}\right )](https://tex.z-dn.net/?f=TSA%3D2%5Cleft%20%28%20%5Cfrac%7B7%7D%7Bh%7D%2B2h%5Ctimes%20%5Csqrt%7B%5Cfrac%7B7%7D%7Bh%7D%7D%5Cright%20%29)
![TSA=2\left ( \frac{7}{h}+2\sqrt{7h}\right )](https://tex.z-dn.net/?f=TSA%3D2%5Cleft%20%28%20%5Cfrac%7B7%7D%7Bh%7D%2B2%5Csqrt%7B7h%7D%5Cright%20%29)
Answer:
the distance is 5
Step-by-step explanation:
Distance (d) = √(-5 - -8)2 + (2 - -2)2
=√(3)2 + (4)2
=√25
=5
dont get confused by whats uptop
but the answer should be 5
