The value of expression 2a ^ 2 + 2b ^ 2 - ab for a-2, b-lis (a) 2 (b) 8 (c) 6 (d) 10
Answer:
[tex]2a^2 + 2b^2 - ab[/tex] [tex]= 8[/tex]
Step-by-step explanation:
Given
[tex]2a^2 + 2b^2 - ab[/tex]
Required
Evaluate when [tex]a=2\ and\ b=1[/tex]
To do this, we simply substitute 2 for a and 1 for b in [tex]2a^2 + 2b^2 - ab[/tex]
[tex]2(2)^2 + 2(1)^2 - 2 * 1[/tex]
[tex]2*4 + 2*1 - 2 * 1[/tex]
[tex]8 + 2 - 2[/tex]
[tex]8[/tex]
Hence:
[tex]2a^2 + 2b^2 - ab[/tex] [tex]= 8[/tex]
when [tex]a=2\ and\ b=1[/tex]

Cam is 3 years older than Lara, If there combined age is 63, determine their ages by solving simultaneous elmination.
Answer:
30 and 33 years
Step-by-step explanation:
Let Lara be x years
Cam =x+3
x+x+3=63
2x+3=63
2x=63-3
2x=60
x=60/2
x=30
Lara=30years and Cam =30+3+33years
Answer:
Lara 30 years, Cam 33 years
Step-by-step explanation:
denote x being the age of Lara
denote y being the age of Cam
Cam is 3 years older than Lara, so
y = x + 3
their combined age is 63 so
x + y = 63.
solving can be done by plugging in y = x+3, then
x + (x+3) = 63, which gives x = 30.
So Lara is 30 years.
Cam is 3 years older, so Cam is 33 years

Answer:
f(-2x+1)=-x -1/2
Step-by-step explanation:
f(-2x+1)= 1/2 * ( -2x + 1 ) - 1
f(-2x+1)=-x + 1/2 - 1
f(-2x+1)=-x -1/2

-The polynomial has 5 terms.
-The leading coefficient is -2.
-The degree of the polynomial is 7.
-The constant term is 4.
Step-by-step explanation:
A polynomial is an expression which has many terms. Each term is separated by addition or subtraction. The standard form of a polynomial is and is written in descending order by exponent. The highest exponent is known as the degree of the polynomial. The leading term at the beginning has a leading coefficient.
Using the information above, select what applies for -2xy^5+3x^7-10x^3y^6+8x^6+4.
-The polynomial has 5 terms.
-The leading coefficient is -2.
-The degree of the polynomial is 7.
-The constant term is 4.
-The polynomial is in decreasing degree order.

Consider the square with vertices at (3, 3), (−3, 3), (−3, −3) and (3, −3). How many points with integer coordinates lie strictly in the interior of this square?
Answer:
The number points with that lie strictly in the interior of the square are 25 points
Step-by-step explanation:
The vertices of the square are; , (3, 3), (-3, 3), (-3, -3) and (3, -3)
From the attached diagram of the square created with Microsoft Word, where one box is equal to one unit, the number of points with integer coordinates that lie strictly in the interior of the square are given by the number of intersecting grid lines
The number of points on the interior of the square = 25 points
The points includes;
(-2, 2), (-1, 2), (0, 2), (1, 2), (2, 2)
(-2, 1), (-1, 1), (0, 1), (1, 1), (2, 1)
(-2, 0), (-1, 0), (0, 0), (1, 0), (2, 0)
(-2, -1), (-1, -1), (0, -1), (1, -1), (2, -1)
(-2, -2), (-1, -2), (0, -2), (1, -2), (2, -2).
URGENT ! what is the common difference of the arithmetic series 14+12+10+8
Explanation:
An arithmetic sequence has a common difference, meaning you use addition or subtraction to get from term to term, and each term in the sequence is an equal distance apart.
A geometric sequence has a common ratio, meaning that you use multiplication or division to get from term to term.
If you look at this sequence:
14-2 = 12
12-2 = 10
10-2 = 8
8 -2 = 4
etc.
Because you are subtracting 2 each time, 2 is the common difference, and the sequence is arithmetic.
If f(x)= 2x+5 and g(x)= 3x2 +2x+5, what is f(3)+g(2)?
Answer:
32
Step-by-step explanation:
1. find f(3) = 2x + 5
a) y = 2(3) + 5
b) y = 6 + 5
c) y = 11
2. find g(2) = 3x² + 2x + 5
a) y = 3(2)² + 2(2) + 5
b) y = 3(4) + 4 + 5
c) y = 12 + 4 + 5
d) y = 21
3. add f(3) + g(2)
a) 11 + 21
b) = 32
