factor the trinomial
2x^2+10x+8
Answer:
x^2 + 5x + 4
Step-by-step explanation:
divide everything by 2
Answer:
2(x+4)(x+1)
Step-by-step explanation:
2x^2+10x+8
1. Take out the greatest common factor. Divide by 2
2(x^2+5x+4)
3. Replace 5x with 1x+4x
2(x^2+1x+4x+4)
4. Spilt the equation in half and factor.
2(x^2+1x) = 2(x(x+1) and 4x+4 = 4(x+1)
5. Combine the new terms
2(x+4)(x+1)
find the area of the minor sector
1 r=9cm,tita=70
Answer:
The area is 49.5 cm^2
Step-by-step explanation:
To find the area of the sector, we are going to use the formula for the area of a sector
Mathematically, we have this as;
A = theta/360 * pi * r^2
r = 9 cm and theta = 70
Substituting these values
A = 70/360 * 3.142 * 9^2
A = 49.5 cm^2

F is directly proportional to a.
If F = 28 when a = 7 find,
F when a = 10
Answer:
Step-by-step explanation:
a=10
Step-by-step explanation:
The question can be interpreted as
F∝a
If we introduce proportionality constant k, we have
F= k.a
28= k. 7
k= 28/7
k= 4
Then the equation can be written as
F= 4.a
To find, a when F = 40?
F= 4.a
40=4 × a
a= 40/4
a= 10
Answer:
F = 40
Step-by-step explanation:
Given F is directly proportional to a then the equation relating them is
F = ka ← k is the constant of proportion
To find k use the condition F = 28 when a = 7 , then
28 = 7k ( divide both sides by 7 )
4 = k
F = 4a ← equation of proportion
When a = 10, then
F = 4 × 10 = 40

Write a quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2
Please I really need your help for this
Let's write -9 where we see A:
-9x² + bx + c = 0Let's write 0 where we see B:
-9x² + 0.x + c = 0(Since B = 0, when it is multiplied by x, it becomes 0 again)
-9x² + c = 0Let's write -2 where we see C:
-9x² + -2 = 0Now we can move on to solving our equation:)
Let's put the known and the unknown on different sides:
(-2 goes to the opposite side positively)
-9x² = 2(it goes as a division because it is in the case of multiplying -9 across)
x² = 2/-9

Greetings from Turkey:)#XBadeXThe quadratic equation ax²+ bx + C = 0, whose coefficients are a = -9, b = 0, c = -2 will be -9x² + -2 = 0
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,coefficients fore the equation,ax²+ bx + C = 0, is a =-9, b = 0, c = -2
We have to write a quadratic equation as,
Any equation of the form ax²+bx+c=0 where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
ax² + bx + c = 0
-9x² + 0x + (-2) = 0
-9x² + -2 = 0
-9x² + -2 = 0
Thus, the quadratic equation ax²+ bx + C = 0, whose coefficients are a =-9, b = 0, c = -2 will be -9x² + -2 = 0

Someone :) is there anyone know what is the answer?
Answer:
answers are below
Step-by-step explanation:
a. -6 ≤ 3x < 15
steps in order to solve:
-6 ≤ 3x
= -6/3 ≤ 3x/3
= -2 ≤ x
3x < 15
= 3x/3 < 15/3
= x < 5
=> -2 ≤ x < 5
b. -3 < 2x - 1 < 7
steps in order to solve:
-3 < 2x - 1
= 1 - 3 < 2x - 1 + 1
= -2 < 2x
= -2/2 < 2x / 2
= -1 < x
2x - 1 < 7
= 2x - 1 + 1 < 7 + 1
= 2x < 8
= 2x/2 < 8/2
= x < 4
=> -1 < x < 4
c. 7 < -3n + 1 ≤ 13
steps in order to solve:
7 < -3n + 1
= -1 +7 < -3n + 1 - 1
= 6 < -3n
= 6/-3 < -3n/-3
= -2 > n
-3n + 1 ≤ 13
= -3n + 1 - 1 ≤ 13 -1
= -3n < 12
= -3n/-3 < 12/-3
= n > -4
=> -4 < n < -2

check whether x² +4x +4 is prefect spuare expression or not . if so factorise the expression
Answer:
It is a perfect square expression.
It factors to (x+2)^2
===========================================================
Explanation:
The general format for a perfect square is
(a+b)^2 = a^2 + 2ab + b^2
Which can be seen through the use of the FOIL rule.
Compare x^2+4x+4 with a^2+2ab+b^2, and we have these three equivalences:
x^2 = a^2 .... first terms4x = 2ab .... middle terms4 = b^2 .... last termsSince x^2 = a^2, we can apply the square root to both sides to get a = x. Similarly, 4 = b^2 leads to b = 2. We could get b = -2, but that would mean 2ab = 2x*(-2) = -4x instead of 4x. So we'll stick with b = 2 instead.
Because a = x and b = 2, we then can say:
(a+b)^2 = a^2 + 2ab + b^2
(x+2)^2 = x^2 + 2*x*2 + 2^2
(x+2)^2 = x^2 + 4x + 4
Showing that x^2+4x+4 factors to (x+2)^2.
