Answer:
Step-by-step explanation:
1) Step 4: Marc has converted radical form to exponent form
Step 5: He has evaluated the value of the radical
3)
![x = \sqrt[3]{8}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B8%7D)
Here, 3 is index and 8 is radicand.
Prime factorize 8 and for every 3 numbers we can take one number outside the radical
Solution:
![x = \sqrt[3]{2*2*2}\\\\x = 2](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B2%2A2%2A2%7D%5C%5C%5C%5Cx%20%3D%202)
4) No,my equation does not have an extraneous solution.
My solution, satisfies the equation
Answer:
It's letter C (x = -2) (y = 1)
Step-by-step explanation:
68/80*100= 85%
This means the current pierce is 85% of the original
100- 85= 15
15% percentage decrease
Answer:
- 14.04 cm²
- 34 cm²
Step-by-step explanation:
1. The area of a parallelogram is the product of its base length and height:
A = bh = (2.7 cm)(5.2 cm) = 14.04 cm²
__
2. The area of a triangle is half the product of its base length and height:
A = (1/2)bh = (1/2)(17 cm)(4 cm) = 34 cm²
