Answer with explanation:

Jean add two numbers , 35 and 9.

Suppose we can write this in word problem as,→There are two trees,A and B, one has 35 mangoes on it and another bears 9 mangoes.How many mangoes are in all?

Solution:

Number of mangoes on tree A=35

Number of mangoes on tree B=9

total number of mangoes on both the trees is given by,x, by the equation

x= A + B

x= 35 +9

x=44

We have used here two operation , =(equality sign), and , +(addition).

Consider the quadratic equation x2 = 4x - 5. How many solutions does the equation have?
JulijaS [17]

Answer:

  • no real solutions
  • 2 complex solutions

Step-by-step explanation:

The equation can be rearranged to vertex form:

  x^2 -4x = -5 . . . . . . . . . subtract 4x

  x^2 -4x +4 = -5 +4 . . . . add 4

  (x -2)^2 = -1 . . . . . . . . . show the left side as a square

  x -2 = ±√-1 = ±i . . . . . . take the square root; the right side is imaginary

  x = 2 ± i . . . . . . . . . . . . . add 2. These are the complex solutions.

<em>Comment on the question</em>

Every 2nd degree polynomial equation has two solutions. They may be real, complex, or (real and) identical. That is, there may be 0, 1, or 2 real solutions. This equation has 0 real solutions, because they are both complex.

Can someone explain what the answer is to this and how? Thank u!!!
Sloan [31]
The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)

alisha [4.7K]

Answer:

2 candies were left.

Step-by-step explanation:

Number of bags of candies = 4 bags

Number of candies in each bag = 18 candies

Total number of candies = 4(18)=72

Ms. Rogers put an equal number of these candies into each of 7 gift boxes.

Divide 72 by 7

72 = 7(10) + 2

Here, remainder is 2.

So,

2 candies were left.

Solve the equation 24+0.44x=19+1.69x
vichka [17]

Answer: X= 4

Step-by-step explanation:

24+0.44x=19+1.69x exp equation like:

24+44x/100=19+169x/100

Multiply left and right side of equation with 100

2400+44x=1900+169x

2400-1900=169x-44x

500=125x

x=500/125

x=4
