Step-by-step explanation:
after rationalising we get as b)19
multiply 3√3+2√2 on numerator and denominator
7(3√3+2√2)/(3²*3-2²*2)
7(3√3+2√2)/27-8
7(3√3+2√2)/19
so denominator is 19
Answer:
(2x+5)(3x-2)
Step-by-step explanation:
6x²+11x-10
6x²+15x-4x-10
3x(2x+5)-2(2x+5)
(2x+5)(3x-2)
1. You could plug this into the calculator as either 70% of 156.33 or 0.7 × 156.33, but either way you know the discount is going to be $109.43
2. We got the discount, so all you have to do is subtract it from the original. 156.33 - 109.43 = $46.90 which is the sale price! I hope this helps
