2√5(√3+3√5)
(1.73+3+2.23)= (6.96)
2√5= 4.23
4.23(6.96)= 29.44
Factors of 40: (1, 40) (2, 20) (4, 10) (5, 8)
---Using these factors will help us find a pair that adds up to -13 and multiplies to equal 40
-5 + -8 = -13
-5 x -8 = 40
(v - 8)(v - 5)
The trinomial can be factored into the following expression (v - 8)(v - 5).
Hope this helps!
Answer:
(1,2) and (2,-1)
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line 
---->inequality B
The solution of the inequality B is the shaded area above the dashed line 
The solution of the system of inequalities is the triangular shaded area between the two dashed lines
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area
Two points in the solution are(1,2) and (2,-1)see the attached figure
Answer:
R + 5b = 300
Step-by-step explanation:
Rogers steps include a scale holding five bricks of equal weight and the scale reads 300 pounds.
We want to write an equation relating Rogers weight and the weight of the bricks to the total weight of the bricks to the total weight shown on the scale.
We have been told to use R for Rogers weight and b for the weight of a single brick.
Since Rogers is holding 5 bricks, the weight of 5 bricks will be 5b.
The sum of Rogers weight and the five bricks is equal to 300 pounds.
Therefore, the equation relating them is:
R + 5b = 300
