Answer:
0.9
Step-by-step explanation:
The equivalent value of the expression 1.8-0.9 = 0.9
Given data:
The first decimal number is represented as p.
The value of p = 1.8
The second decimal number is represented as q.
The value of q = 0.9
The expression A = p - q
On simplifying the equation:
A = 1.8 - 0.9
On subtracting both the decimals:
A = 0.9
Therefore, the value of A is 0.9
Hence, the expression is A = 0.9

I need help with this what is the awnser
Answer:
x = 23
Step-by-step explanation:
For this figure, we know we are dealing with a 90 degree angle since there is a small square in the figure, therefore we can set up the equation...
65 + (x + 2) = 90
In this sense, the parenthesis are unnecessary.
67 + x = 90
-67 -67
x = 23
Hope this helps!

It will basically be converted into a decimal.
what number must you add to complete the square?
x^2+14x=3
Answer: 49
Step-by-step explanation: In order to complete the square, you need a perfect square trinomial on the left side of the equation.
The question is, what is the number we need?
Well it comes from a formula. The number that is added to both sides
comes from half the coefficient of the middle term squared.
So that's half of 14 which is 7, squared which is 49.

Which one of the points A(5.2). B(6,-3) and C(4.7) is the mid-point of the other two? Check your answer by calculating two distances.
Answer:
A is the midpoint
Step-by-step explanation:
Given
A(5.2) B(6,-3) and C(4.7)
Required
Which is the midpoint
Midpoint is calculated using:
[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
Testing A as the midpoint, we have:
[tex](5,2) = \frac{1}{2}(6+4,-3+7)[/tex]
[tex](5,2) = \frac{1}{2}(10,4)[/tex]
[tex](5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)[/tex]
[tex](5,2) = (5,2)[/tex]
The above equation is true. Hence, A is the midpoint of B and C
3. Explain why the polynomial 34 + 5x3 - 7x2 + 3x has a degree 3 and not 4.
Answer:
See explanation below
Step-by-step explanation:
The degree of a polynomial is the LARGEST power at which the variable/s appear in their expression.
Notice that in the given polynomial, the highest power for the variable x is 3, from the term 5 x^3.
There is no other term with higher power for x.
The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .
We have to explain, why the polynomial [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] has a degree 3 and not 4.
According to the question,
A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.
The degree of a polynomial is the largest power at which the variable appear in their expression.
[tex]Polynomial = 3^{4} + 5x^{3} + 7x^{2} + 3x[/tex]
The given polynomial, the highest power for the variable x is 3, from 5 .
Hence, The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .
