What values are the solutions for x2 + 2x = 8?
Answer:
x=4,-2 hope this helps!!
Step-by-step explanation:
Solve the inequality 3x + 4 < 22
Answer:
3х<18
х<6
хє(-infinity ;6);
Answer:
x<6
Step-by-step explanation:
3x+4<22
First, subtract 4 from both sides of the inequality.
3x-4<22-4
This cancels out the 4, so the 3x is isolated
3x/3<18/3
Finally, simplify to get the answer.

3/4
Answer: 1 2/7, 7/9,3/4
Step-by-step explanation: 9/7 you had to make a whole then make the fraction 2/7. 7/9 you literally just had to subtract 8-1 to gt 7 and because the denominator didn't need to change it so that makes it 7/9. And the last one 9/12 well 3 can go into 9 and 12 evenly. For 9 it goes in 3 times and for 12 it goes in 3 to any you get 3/4.
17. The area of the large square below is 49 centimetres squared. What are the side lengths of the shaded triangle?
Answer:
12.25,12.25,7
Step-by-step explanation:
Formula of Area of square= length x breadth
In a square all side are equal as we all know that which means if the Area of the square is [tex]49cm^{2}[/tex] if we take the root of 49 it gives us 7 so the length and breadth of the square is equal to 7 as shown in my figure i uploaded. Please excuse my professional drawing skills ( pun intended :D)
The dotted lines i assume shows that sides are being bisected into two equal halves which means the whole side equals 7cm and the half is 7/2 equals 3.5cm so the bottom half side of the triangle is 7cm but the two slant heights we have to find we can find it by using phythogra's theorem
(Hypotnuse)^2=(Length^2) x (Breadth)^2
we need to find just one side of the hypotnuse/slant height then we multiply it by 2 which would gives us both of our hypotnuse sides so
(Hypotnuse)^2= (3.5)^2 x (3.5)^2
(Hypotnuse)^2=150.0625
Apply square root on both sides gives us
[tex]Hypotnuse = 12.25[/tex]
Since the traingle is covered by two slant height's the sides of the traignle are 12.25cm 12.25cm and 7cm

To make the expression 4x−2+□(2x+4) equivalent to 2(6x+7), what must be the value in the box? PLSSSSS HELLPPP
Answer:
4 goes in the box
Step-by-step explanation:
The solution of the equation 4x − 2 + y(2x + 4) = 2(6x + 7) will be 4.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Let the value inside the box be 'y'. Then the equation is given as,
4x − 2 + y(2x + 4) = 2(6x + 7)
Simplify the equation, then we have
4x − 2 + y(2x + 4) = 2(6x + 7)
4x − 2 + y(2x + 4) = 12x + 14
y(2x + 4) = 8x + 16
y = 4(2x + 4) / (2x + 4)
y = 4
The solution of the equation 4x − 2 + y(2x + 4) = 2(6x + 7) will be 4.

If the CPI changes from 121 to 124 between December 2018 and December 2019, the:
deflation rate for 2019 is 2.4%
inflation rate for 2019 is 4.2%.
inflation rate for 2019 is 2.5%.
deflation rate for 2019 is 3%.
Answer:
Inflation rate for 2019 is 2.5%
Step-by-step explanation:
(124/121) - 1 = 1.02479 - 1 = .02479
Change 0.02479 to percent by multiplying 100 = 2.479%
Round this up to 2.5%
Since the value is increasing from 121 in 2018 to 124 in 2019, this is an inflation.

The coordinate grid shows points A through K.

Answer:
I think that it could be A, or the third choice.
We need to see which points are solutions for the given system of inequalities, thus the solutions are points B and L.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Solving a system of inequalities we have the system here;
y <-2x + 10
y < 1/(2x - 2)
A point is a solution of the system if and only if it is a solution for both inequalities.
Now, Shade the region below the like for x = 5.
y = -2(5) + 10
= -10 + 10
= 0
For x= 0
y = -2(0) + 10
= 0 + 10
= (0, 10)
The diagram is attached below.
So, only B and L are solutions for the system.

If the total income generated from gasoline for AER was 408 million how much would the cost forna barrel of gasoline
Answer:
kkkkk
Step-by-step explanation:
kkkkkk kkkkkk kkkWhy were the Punic War so important for the development of the Roman Empire?
Answer:
20
Step-by-step explanation:
If you have 60,000,000 barrels of crude oil and 34% of the barrels are gasoline then you have to set up the problem like this because you have to find out how much 34% of 60,000,000 is first in order to solve the problem.
is/of x 100/%
60,000,000 / a X 100 / 34
so..60,000,000 x 34 = 2,040,000,000
then divide that amount by 100= 2,040,000,000 / 100 = 20, 400,000
so the 34% actually is the total 20,400,000. Now, you divide the dollar amount 408,000,000 million barrels by the total amount of gasoline which is 20,400,000.
408,000,000 / 20,400,000 = 20
So each barrel of gasoline cost $20.
