Hi Brainiac
4x-5=2(2x+1)
Distribute
4x-5= (2)(2x)+(2)(1)
4x-5=4x+2
Subtract 4x
4x-5-4x= 4x+2-4x
-5=2
Add 5
-5+5=2+5
0=7
There are no solutions
I hope that's help:0
Answer: 41.08
Step-by-step explanation:
The product of 3a + 5 and 2a2 + 4a – 2 is , the correctoption is A.
When two algebraic expressions are multiplied, the result is called the product, and the two expressions making up the product are called factors and multiplicands.
The multiplication of two algebraic equations can be expressed as a × b.
The product of 3a + 5 and 2a2 + 4a – 2 is determined in the following steps given below.
Hence, the product of 3a + 5 and 2a2 + 4a – 2 is .

Answer:
6a3 + 22a2 + 14a - 10
Step-by-step explanation:
(3a + 5) x (2a^2 + 4a - 2)
= 3a(2a^2 + 4a - 2) + 5(2a^2 + 4a - 2)
= 6a^3 + 12a^2 - 6a + 10a^2 + 20a - 10
= 6a^3 + 22a^2 + 14a - 10
Answer:
Step-by-step explanation:
let the 3rd side, the hypotenuse, be x
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 2² + 3² = 4 + 9 = 13 ( take square root of both sides )
x =
Answer:
Step-by-step explanation:
It is a right triangle and you have the measure of the cathets, we use the Pythagorean theorem
√(3² + 2²) =
√(9 + 4) =
√13
y=-x+3
y=x-3
A) The sample is the math questions in the study.
B) The sample is the responses of the volunteers in the study.
C) The sample is the amount of sleep the volunteers got in the study.
D) The sample is the sleep-deprived participants in the study.
2) What is the sample's population?
A) The population is the collection of all the math questions from the math test.
B) The population is the collection of the responses of all individuals who completed the math test.
C) The population is the collection of all the individuals who completed the math test.
3) Which part of the study represents the descriptive branch of statistics?
1) Identify the sample used in the study: B) The sample is the responses of the volunteers in the study
2) What is the sample's population: B) The population is collected of the response of all individuals who completed the math test
3) Which part of the study represents the descriptive branch of statistics:
individuals who are not sleep deprived will be more likely to answer math questions correctly than individuals who are sleep deprived.
