Answer:

The answer to your question is below

Step-by-step explanation:

1.- (x + 2)(x + 4) = x² + 4x + 2x + 8 = x² + 6x + 8

2.- (m - 5)(m + 2) = m² + 2m - 5m - 10 = m² - 3m - 10

3.- (2x + 3)(4x - 2) = 8x² - 4x + 12x - 6 = 8x² + 8x - 6

4.- (2r - 3)(r + 12) = 2r² + 24r - 3r - 36 = 2r² + 21r - 36

6.- (k - 3)(k - 1) = k² - k - 3k + 3 = k² - 4k + 3

Hi everyone I really need help on number 33 and 34 I would really appreciate it
seraphim [82]
For the first one: A=pi*r^2*1/8 (1/8 becuase we are finding the area of one pane)
A=pi*16/8
A=2pi

For the second one: First do the larger circle minus the smaller circle (pretend they are whole circles)
A(larger)=pi*18^2
=324pi

A(smaller)=pi*8^2
=64pi

A=324pi-64pi =260pi

Now, a whole circle is 360 degrees so 150 degrees is 5/12 of a circle. We take 5/12 of 260pi to get the answer

260pi*5/12=340.3

1.678 rounded to the nearest hundredth​
Talja [164]

Good morning,

Answer:

1.678 rounded to the nearest hundredth is 1.68

Step-by-step explanation:

By looking at the number 1.678 it’s clear that the hundredth digit is 7

since 8∈{5,6,7,8,9} then we delete the 8 and add one to 7

we get 1.68 .
