Answer:
(x-4)(x-3)
Step-by-step explanation:
x²- 7x+12
=x²-4x-3x+12 applying midterm break
=x(x-4) -3(x-4)
=(x-4)(x-3)
Answer:
24) x = 9.2
25) x = 30.8
Step-by-step explanation:
Given
See attachment for triangles
Solving (24)
To solve for x, we make use of cosine formula
i.e.
cos(40) = adjacent ÷ hypotenuse
So, we have:
cos(40) = x ÷ 12
Multiply both sides by 12
12 cos(40) = x
12 * 0.7660 = x
x = 9.2
Solving (25)
To solve for x, we make use of sine formula
i.e.
sin(25) = opposite ÷ hypotenuse
So, we have:
sin(25) = 13 ÷ x
Multiply both sides by
x sin(25) = 13
Divide by sin(25)
x = 13 ÷ sin(25)
Using a calculator
x = 30.8
Using JAVA:
int sum = 0;
int k = 1;
while(sum <= 2000) {
sum += 3*k*k;
k++;
}
System.out.println(k);
Output: 14
Which means it will take 14 terms for the series to surpass 2000
Answer:
A. How many paperback books each person buys.
Step-by-step explanation:
In the equation the x represents how many paperback books they can buy.
In the equation the 2 represents that 1 hardcover book was purchased.
In the equation the 35 represents how much money they spent in total.
The equation is complete except for x which has to be substituted with how many paperback books they can buy. Which would be 5.
Hope This Helps :)
Answer:
x = −10 and x = 4
Step-by-step explanation:
x2 + 6x = 40
Subtract 40 from each side
x^2 + 6x -40 =0
Factor, what 2 numbers multiply to -40 and add to 6
10 * -4 = -40 10+-4 = 6
(x+10) (x-4) = 0
Using the zero product property
x+10 =0 x-4=0
x=-10 x=4
