Answer:
3b is the answer
3a+2b-3a+b
3a-3a+2b+b
2b+b
Step-by-step explanation:
The first step I did is switch up the equation so that the like terms are next to each other. So the a’s are next to each other and the b’s are next to each other. Then I subtracted 3a-3a and got 0 and in the last step I added the 2b + b and got 3b.
9a^2- 4b^2
First, Apply the distributive property 3a(3a)+3a(−2b)+2b(3a)+2b(−2b)
Second Simplify the term. 3a(3a)+2b(−2b)
Third, Simplify Each term.
3⋅3a2+2b(−2b)
9a2+2b(−2b)
9a2+2⋅−2b2
= 9a2−4b2

Answer:
? = 13
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
?² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )
? = [tex]\sqrt{169}[/tex] = 13
Answer:
13
Step-by-step explanation:
If we use the Pythagorean theorem we have
hypothenuse^2 = 12^2 + 5^2 = 144 + 25 = 169
hypothenuse = √169 = 13

Use inductive reasoning to describe the pattern. Then find the next two numbers in the pattern. 4, 6, 9, 13, . . .
A.
Add 2 to the first term, 3 to the second term and continue, adding 1 more each time; 18, 24.
B.
Add 2 to the previous term; 15, 17.
C.
Add 12 of the previous term; 19.5, 29.25
Answer:
A.
Explanation:
4 goes up 2 to 6. 6 goes up 3 to 9. 9 goes up 4 to 13. Therefore, you can expect 13 to go up 5 to 18, and 18 to go up by 6 to 24.

Gilbert purchased a car for 34000. The car depreciates at a rate of 14% per year. The exponential function that represents this situation is y = 34000(0.86)^x.
What is the change factor for this function?
Answer:
.86
Step-by-step explanation:
Exponential function formula
[tex]y = a ( 1 + or - r ) ^t[/tex]
where a = initial value
r = rate of change
and t = number of years
given the equation y = 34000(0.86)^x.
r = .86
Hence the change factor is .86

If the square below is enlarged by a scale factor of 2, what will be the area of the new square? 184 square units 188 square units 192 square units 196 square units
Answer:
256square units
Step-by-step explanation:
Since we are not given a diagram. Let us assume the side length of the given square is 8 units
If the the square is enlarged by a scale factor of 2, the side length of the new square will be 2 * 8 = 16units
Since area of a square = L²
Hence the area of the new square = 16²
area of the new square = 256 square units
Hence the area of the new square is 256square units
Note that the side length of the original square was assumed. The values can change depending on the side length of the original square before enlargement

Hi, I took the test and this is the answer. If its K12 then I'm 100% its correct.
The values that can be use for a, b and c in the equation 2x² + 7x − 5 = 0 are a = 2, b = 7, c = -5
Quadratic equation formulaThe quadratic equation formula is represented as follows:
ax² + bx + c

Step-by-step explanation:
Find the value of x in the triangle
Answer:
√41
Step-by-step explanation:
Use a² + b² = c²
a = 4
b = 5
4² + 5² = c²
4² = 16
5² = 25
16 + 25 = c²
41 = c²
You need to get ² away from c, so square root both sides.
√41 = √c²
√41 = c
√41 is in its simplest form, so it is left as √41.
