Answer: 32questions
Step-by-step explanation:let the total number of test = x
Therefore: 24/x * 100 = 75
x = 24*100 / 75
= 32questions
Answer:
-6x (x + 1)(x - 1)
Explanation:
Before we begin, remember the following:
(-ve) * (-ve) = +ve
(-ve) * (+ve) = -ve
(+ve) * (+ve) = +ve
(+ve) * (-ve) = -ve
a² - b² = (a + b)(a - b)
Now, for the given:
(4x³ + 3x² - 6x) - (10x³ + 3x²)
First, we eill remove the brackets based on the rules mentioned above. This will give us:
4x³ + 3x² - 6x - 10x³ - 3x²
Now, we will combine like terms as follows:
(4-10)x³ + (3-3)x² - 6x
-6x³ - 6x
Taking -6x as a common factor:
-6x (x² - 1)
Factoring the bracket as difference between two squares will give us the final simplest form:
-6x (x + 1)(x - 1)
Hope this helps :)
Answer:
False
Explanation:
No, a triangle cannot be constructed with sides of 2 in., 3 in., and 6 in.
For three line segments to be able to form any triangle you must be able to take any two sides, add their length and this sum be greater than the remaining side.
Answer:
g = 12.7 cm
Step-by-step explanation:
Here, we want to find the length of the side g
To do this, we shall employ the use of the cosine rule
Mathematically, by using the general form of the rule, we have it that ;
g^2 = e^2 + f^2 -2efCosG
So we have;
g^2 = (9.8)^2 + (3)^2 - 2(9.8)(3) cos 167
g^2 = 162.33
g = √162.33
g = 12.7
