(6r - 1)(-8r - 3)
= -48r^2 - 18r + 8r + 3
= -48r^2 - 10r + 3
I hope this helps.

.. a)

Answer:

1100

Step-by-step explanation:

price = 1500

discount= 15%

15% of 1500 = (15/100)*1500= 15*15= 225

so selling price = 1275

profit is selling price - cost price

1275 - CP = 175

CP = 1275-175= 1100

I didn't understand the calculator part of the question

Step-by-step explanation:

given,

measures of 3 angles of triangle,

angle 1 = 3x

angle 2 = 2x + 15°

angle 3 = 3x + 5 °

sum of the angles should be 180°

so,

angle 1 + 2 + 3 = 180°

after inserting the values we got,

3x + 2x + 15 + 3x + 5 = 180°

→ 8x + 20 = 180°

→ 8x = 180 - 20 = 160°

→ x = 160/8 = 2

→ x = 20

therefore,

angle

1 = 3x = 3 × 20 = 60

2 = 2x + 15 = 2(20) + 15 = 55°

3 = 3x + 5 = 3(20) + 5 = 65°

as given,

their sum should be 180° so,

60 + 55 + 65 = 180°

hope this answer helps you dear....

I guess dear the measure of the angles of traingle have x in their expression!...if they have than this is the answer!

4x^2 + 9xy − y^2 = 8 implicit differentiation

Alexus [3.1K]

4x^2 + 9xy - y^2 = 8
8x + 9xf'(x) + 9y - 2yf'(x) = 0
f'(x) (2y - 9x) = 8x + 9y
f'(x) = (8x + 9y)/(2y - 9x)

You have 500 sheets of notebook paper. After 1 week, you have 72% of the sheets left. You use the same number of sheets each wee

NISA [10]

You use 28% of your available sheets
28% = .28
500 x .28 = 140 sheets used

(0,500) (1,360)

m = 360-500/1-0
m = -140

y = -140x + 500
