The number in exponential form should have an exponent of 3 so x^3 equals 3^3 (3×3×3=27). Since the exponent is the same, set the bases equal. Answer: A. X=3
Answer:
27/16
Step-by-step explanation:
1/2+3/4+7/16=...
8/16+12/16+7/16=27/16
Answer:
5.5
Step-by-step explanation:
Add the two then divide by 2
7.5 +3.5= 11
11÷2= 5.5
Answer:
Step-by-step explanation:
Use FOIL method.First multiply (5x + 1) and (3x - 4). Then multiply (15x² - 17x - 4) by (x +2)
Volume of the rectangular prism = length *width * height
= (5x + 1) (3x -4)(x +2)
= [ 5x*3x + 5x*(-4) + 1*3x + 1*(-4) ] (x + 2)
= [15x² <u>- 20x + 3x</u> - 4] (x +2) {Combine like terms}
= [15x² - 17x - 4] (x + 2)
=[15x² -17x - 4]*(x) + [15x² - 17x -4]*2
= [15x²*x - 17x*x - 4*x ]+ 15x²*2 - 17x *2 - 4*2
= 15x³ - 17x² - 4x + 30x² - 34x - 8
= 15x³ <u>- 17x² + 30x²</u> <u>- 4x - 34x </u>- 8 {Combine like terms}
= 15x³ + 13x² - 38x - 8
