Answer:
(x + 4)(5x - 4)
Step-by-step explanation:
[tex]5x^2 + 16x – 16 \\ = 5x^2 + 20x - 4x– 16 \\ = 5x(x + 4) - 4(x + 4) \\ = (x + 4)(5x - 4)[/tex]
Answer:
(5x - 4) • (x + 4)
Step-by-step explanation:
Multiply the coefficient of the first term by the constant 5 • -16 = -80
Find two factors of -80 whose sum equals the coefficient of the middle term, which is 16 .
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 20
5x2 - 4x + 20x - 16
Add up the first 2 terms, pulling out like factors :
x • (5x-4)
Add up the last 2 terms, pulling out common factors :
4 • (5x-4)
Add up the four terms of step 4 :
(x+4) • (5x-4)
Which is the desired factorization

Sandra prepared 15 kilograms of dough after working 3 hours. How many hours did Sandra
work if she prepared 20 kilograms of dough? Solve using unit rates.
hours
Answer:
4 hours
Step-by-step explanation:
4 hours because if 15 is 3 hours. count by 5. 5 kilograms of dough would be 1 hour, 10 kilograms of dough would be 2 hours leaving 15 at 3 hours and 20 kilograms at 4 hours.

4. If f(x)=2x+3(x+4)+5 then f(6)=?
Answer:
f(6)=42
Step-by-step explanation:
We know that the equaiton is f(x)=2x+3(x+4). So that means when it is f(6), we plug in 6 into all of the x. Therefore, the equation will be f(6)=2(6)+3(6+4). We combine like terms to get f(6)=12+3(10). We do 3x10 which is equal to 30. f(6)=30+12. 30+12=42. f(6)=42. Therefore, f(6)=42.
If this has helped please mark as brainliest
Answer: 47
Step-by-step explanation:
That just means replace the x’s with 6 in the equation. So 2*6+3(6+4)+5. 6+4 is 10, 2*6 is 12. So the equation is now 12+3(10)+5. 3*10 is 30. 12+30+5=47.
Kevin is rolling two dice together and adding them up. Which sums should come up the most frequently?
Answer:
7 occurs most frequently.
Step-by-step explanation:
If we roll two dice, we do get sample space as
(1,1) = 1+1 =2 (4,1)=4+1=5
(1,2)= 1+2 =3 (4,2)= 34+2=6
(1,3)= 1+3=4 (4,3)= 4+3=7
(1,4)=1+4=5 (4,4)= 4+4=8
(1,5)=1+5=6 (4,5)= 4+5 =9
(1,6)=1+6=7 (4,6)= 4+6=10
(2,1)= 2+1=3 (5,1)= 5+1=6
(2,2)=2+2=4 (5,2)=5+2 =7
(2,3)= 2+3=5 (5,3) =5+3=8
(2,4)=2+4=6 (5,4) =5+4 =9
(2,5)=2+5=7 (5,5)=5+5=10
(2,6)=2+6=8 (5,6)=5+6=11
(3,1)=3+1=4 (6,1)= 6+1=7
(3,2)=3+2=5 (6,2)=6+2=8
(3,3)=3+3=6 (6,3)=6+3=9
(3,4)=3+4=7 (6,4) =6+4 =10
(3,5) =3+5=8 (6,5)=6+5=11
(3,6)=3+6=9 (6,6)=6+6=12
2 occurs for 1 time
3 occurs for 2 times
4 occurs for 3 times
5 occurs for 4 times
6 occurs for 5 times
7 occurs for 6 times
8 occurs for 5 times
9 occurs for 4 times
10 occurs for 3 times
11 occurs for 2 times
12 occurs for 1 time.
So, 7 occurs most frequently.
The following tables show some values from three different functions. which of these functions could be quadratic?
Answer:
C. III only
Step-by-step explanation:
a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.
so, let's look at the tables.
table I shows the powers of 2. y = 2^x
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
so, it is not saying anything in general.
table II shows an "identity" equation. y = x
0 = 0
1 = 1
2 = 2
3 = 3
this does not square anything.
table III shows then finally a square equation. y = x^2
0^2 = 0
1^2 = 1
2^2 ≈ 4
3^2 = 9
hurray !

Answer:
(7, 4)
Step-by-step explanation:
The solution to the system of the 2 equations represented on the graph by the two lines is the c
x and y coordinates of the point where the two lines intersect.
They intersect at when x = 7, y = 4.
Therefore, the solution to the system of equations would be (7, 4).

Find m
Answer:
D. 70.53
Step-by-step explanation:
To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]
Substitute,
[tex]cos(CBA) = \frac{3}{9}[/tex]
Simplify
[tex]cos(CBA) = \frac{1}{3}[/tex]
Inverse operations,
[tex]CBA=cos^-1(\frac{1}{3})[/tex]
Compute,
m<CBA = 70.53
