Answer:
x²+3x+3
Step-by-step explanation:
(x+2)(x+1)
x²+x+2x+3
=x²+3x+3
Answer:
x² + 3x + 2
Step-by-step explanation:
Given
(x + 2)(x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 1) + 2(x + 1) ← distribute both parenthesis
= x² + x + 2x + 2 ← collect like terms
= x² + 3x + 2

What is Associative Property?The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
Given:
We have (3 x 8) x 4 = 3 x ( )
We know from associative Property
a x ( bx c) = (a x b) x c
Here a= 3, b=8 and c= 4
So, (3 x 8) x 4 = 3 x ( 8 x 4).

2. In right triangle RST with right angle S the m4R = 24°. What is the
measure of T?*
о
24°
O 56°
0 66°
O 116°
Sum of the interior angles of any triangle equal 180° ;
So :
90° + 24° + T = 180°
114° + T = 180°
subtract both sides 114
T = 180° - 114°
T = 66°

Two years ago a company purchased 500 dozen pencils at 40 cents per dozen. This
year, only 75% as many pencils were purchased as were purchased two years ago, but
the price was 20% higher than the old price. What was the total cost of pencils
purchased by the company this year?
Answer:
180$
Step-by-step explanation:
First you have to find out how many pencils the company bought each year which is 6000 since they bought 500 dozens and 75% of 500 is 375 and 20% of 0.40 is 0.08 so the cost for each dozen pencils would be 180$ (Sorry if this is wrong I'm 80% sure)
PROBLEM 1
Peter has many socks, all the same except that they are in three different colours. He is leaving to catch an early train to go on a business trip, and he does not want to wake his wife, so he packs in the
dark. He needs eleven pairs of socks, each sock in each pair the same colour. How many socks must he take from his drawer to be sure of achieving this?
Answer:
24 socks
Step-by-step explanation:
The given parameters are;
The number of different colors of socks = 3
Therefore, we have the worst case, the first three socks are different colors, since there are three different colors, the fourth socks is first pair in the worst case scenario
After which, every other two socks makes a pair in the worst case process, the number of socks he must take to make sure he has eleven pairs are given by the pairing table
Number of socks 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
Number of pairs 0 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11
Therefore, he must take 24 socks to make sue he has 11 pairs of the same color.
The 6th graders brought in 56 boxes of tissues 48 pads of loose leaf and 16 rolls of toilet paper. The t acher wants to divide the materials into the greatest amount of containers but wants each container to look the same how many containers can they fill how many of each item will be inside the containers
Answer:
The greatest amount of containers with each container to looking the same is 8 containers.
Step-by-step explanation:
We have:
56 boxes of tissues
48 pads of loose leaf
16 rolls of toilet paper.
To find the greatest amount of containers with each container to looking the same we apply the greatest common factor method
Step 1
We list the factors of 16, 48 and 56
The factors of 16 are: 1, 2, 4, 8, 16
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
The greatest common factor is 8.
Hence, the greatest amount of containers with each container to looking the same is 8 containers.

Fabio is driving west away from Albany and towards buffalo along interstate 90 at a constant rate of speed of 62 miles per hour. After driving for 1.5 hours Fabio is 221 miles from Albany
Answer:
The distance between Albany and Buffalo along the I90 is 288.8 mi.
The speed of Fabio is 62 mph.
After 1.5 hours, he is 221 miles from Albany.
Things we can calculate here:
Using the relation:
Distance = time*speed.
We can calculate the number of miles that he moved in that 1.5 hours.
D = 62mph*1.5h = 93mi.
If after 1.5 hours, he was 221 miles Albany, then before that he was 93 miles closer to Albany.
His initial position was:
221 - 93 = 128 miles away from Albany.
Now we also can calculate the time left to arrive at Buffalo.
We know that the distance between Albany and Buffalo is 288.8 mi
And he is 221 mi away from Albany.
Then the distance left to Buffalo is:
288.8mi - 221mi = 67.8mi
And the time left will be:
Distance/speed = time
67.8mi/62mph = 1.1 hours.
He needs to drive for another 1.1 hours to get to Buffalo.
A type of superglue has a density of 0.86 g/mL. What is the mass of a 150 mL sample of this glue?
Answer: 129g
Step-by-step explanation:
The formula to calculate mass is given as:
m = d × v
where,
m = mass
d = density
v = volume
Mass = dv
