The answer is C)
Step-by-step explanation:
4x(x+1) - (3x-8)(x+4)
(4x^2+4x) - (3x^2+12x-8x-32)
(4x^2+4x - 3x^2-12x+8x+32)
4x^2-3x^2+4x+8x-12x+32
=x^2+32
Quadratic binomial
Answer:
Step-by-step explanation:you flip the second fraction and multiply that
Answer: C) 4.20
Explanation:
Multiply each value with its corresponding frequency:
- 1*450 = 450
- 10*35 = 350
- 50*10 = 500
- 100*4 = 400
- 400*1 = 400
Add up the products
450+350+500+400+400 = 2100
Then divide this over the total frequency (450+35+10+4+1 = 500)
So we get 2100/500 = 4.20 as the expected value.
Answer:
corresponding angle are:
<1=<5
<2=<6
<7=<3
<8=<4
<u><1&<5,<2&<6,<7&<3,<8&<4are pair corresponding angle.</u>
