Answer:
A, B, and E
Step-by-step explanation:
When talking about like terms you need to look at the variable. You have to look at which has the same variables and then you can determine which are like terms.
For A --> -6m + 4m both have m as a variable. They can be combined. Which is why they are like terms. Do the same for the rest.
What would NOT be like terms?
C-- 10m + mn
This is wrong because of the variable. the variable for 10m is m. When there is only a variable you can pretend there is a 1 (For example, m can be 1m but we ignore that). mn is a variable as a whole. So if we added one to the front, the variables of 10m and 1mn would not match! It does not matter if they both have an m, because the value would be different either way.
Hope this helps!!

When Albert was born, he was 19.5 inches "tall". Today, on his 13th birthday, Albert is four feet, nine inches.
How much did he grow:
Per year:
Per month:
Per day:
Per hour:
Answer: 76.5in or 6.37ft
Step-by-step explanation:
You would convert the 4 feet into inches which would be 48in. You would add the 9in and the 19.5in and come up with 76.5in. Then you just convert the 76.5in to 6.375ft

total degree inside pentagon is (n - 2) x 180 = 540
180-62 = 118
180-66 = 114
180-77 = 103
180-59 = 121
118+114+103+121 = 456
540 - 456 = 84
84 + 12x = 180
12x = 180-84
x = 96/12
x = 8
The value of x in the given pentagon is 8.
Option D is the correct answer.
What is a Pentagon?A pentagon is a polygon that has five sides and five angles.
The sides and angles of a pentagon are not all equal unless it is a regular pentagon.
A regular pentagon has five equal sides and five equal angles.
We have,
For a pentagon, n = 5, so we have:
total degree = (5 - 2) × 180 degrees
total degree = 3 × 180 degrees
total degree = 540 degrees
Now,
Each angle makes a straight angle.
So,
77 + a = 180
a = 180 - 77 = 103
59 + b = 180
b = 180 - 59 = 121
c + 66 = 180
c = 180 - 66 = 114
d + 62 = 180
d = 180 - 62 = 118
Now,
a + b + c + d + e = 540
103 + 121 + 114 + 118 + e = 540
e = 540 - 456
e = 84
Now,
12x + 84 = 180
So,
12x = 180 - 84
12x = 96
x = 8
Thus,
The value of x is 8.

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. . 4,2,1,...
Answer: Geometric sequence
Step-by-step explanation:
The common ratio will be:
= 2nd term / 1st term
= 2/4
= 1/2
Also, Using thw 3rd and 2nd term gives:
= 1/2
Common difference will be:
= 2nd term - 1st term
= 2 - 4
= -2
Using thw 3rd and 2nd term gives:
= 1 - 2
= -1
From the above, we can see that it's a geometric progression as the common ratio is thesame.

Kayla uses mental math to find the product of $11.97x5, but she made a mistake.Her steps are shown. Step 1: Round $11.97 to $12. Step 2: multiply $12.00x$5=60 Step 3: subtract $12.00-$11.97 Step 4: subtract $60.00-$3.00=57.00. Select witch one is where Kayla made her first mistake.
Answer:
Step 4.
Step-by-step explanation:
Given that Kayla uses mental math to find the product of $ 11.97x5, but she made a mistake, and knowing that her steps were the following:
Step 1: Round $ 11.97 to $ 12.
Step 2: multiply $ 12.00x $ 5 = 60
Step 3: subtract $ 12.00- $ 11.97
Step 4: subtract $ 60.00- $ 3.00 = 57.00.
To determine in which one is where Kayla made her first mistake, the following reasoning must be performed:
Rounding from 11.97 to 12 implies a difference of 0.03 that must be multiplied by 5, the result of which is 0.15.
Thus, from the result of 12 x 5 (60), 0.15 must be subtracted, and not 3, as was subtracted in Step 4. Therefore, Step 4 is the one where the error occurred.

g(n) = 18 - 4n
Step-by-step explanation:
Given the recursive formula
g(n) = g(n - 1) - 4 with common difference d = - 4 and g(1) = 14
The explicit formula for an arithmetic sequence is
g(n) = g(1) + (n - 1)d , then
g(n) = 14 - 4(n - 1)
= 14 - 4n + 4
= 18 - 4n

In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
Answer:
89.8 feet
Step-by-step explanation:
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
We would solve the above question using Sine rule
The formula is given as:
DB/sin D = BC/sin B
93/sin 90 = BC/sin 75
We cross multiply
sin 90 × BC = 93 × sin 75
BC = 93 × sin 75/sin 90
BC = 89.83 feet
Approximately BC = 89.8 feet

C = 2*pi * r
pi = 3.14
r = d / 2
r = 8/2
r = 4 feet
C = 3.14 * 2 * 4
C = 18.84 feet.
Area
pi = 3.14
r = d/2
r = 8/2
r = 4
Area = 3.14 * 4^2
Area = 3.14 * 16
Area = 50.24 ft^2

The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the length of the dimension of the rectangle.
Answer:
11 ft
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is
A = L * W.
Represent the length, L, by 2W + 1 ("1 more than twice the width"). Then the area formula (above) becomes:
A = 55 ft^2 = (2W + 1)(W), which, when simplified, results in:
2W^2 + W - 55 = 0, whose coefficients are {2, 1, -55}. Let's use the quadratic formula to solve this for W:
The discriminant, b^2 - 4ac, is 1^2 - 4(2)(-55), or 441. The square root of 441 is 21. Thus, the quadratic formula gives us:
-1 ± 21
W = ------------- = (1/4)(-1 + 21), or W = 5 and W = -22/4 = -11/2
2(2)
A measure of length can't be negative, so we reject W = -11/2 in favor of W = 5.
Then, according to the formula for L that we found earlier, L = 2W + 1, or
L = 2(5) + 1, or L = 11.
Check: Does L * W result in an area of 55 ft²? Yes
