Answer:
9x^3-21x^2+19x-6
Step-by-step explanation:
First you have to distribute the first equation into the second since the two are being multiplied:
(3x^2-5x+3)(3x-2)
9x^3-6x^2-15^2+10x+9x-6
(simplify)
9x^3-21x^2+19x-6
Answer:
Yes.
Step-by-step explanation:
You always do the operations in parenthese first.
"The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)." -khanacademy . org > ...> order of operations
Answer:
Step-by-step explanation:
Divide 4378 by 15
From 4378 lets take the first two digits for division:
43/ 15
We know that 43 does not come in table of 15
So we will take 15 *2 = 30
43-30 = 13
The quotient is 3 and the remainder is 13
Now take one more number which is 7 with 13
137/15.
Now 137 does not come in table of 15
15*9 = 135
135-137 = 2
It means quotient is 9 and remainder is 2
Now take one more number which is 8 with 2
28/15
28 does not come in table of 15
15*1 = 15
28-15 = 13/15
Now the quotient is 1 and remainder is 13
Hence, the quotient of 4,378 is 291 and remainder is 13 ....
Using Pythagorean’s theorem, the side length is sqrt(89)
Answer:
0.44
Step-by-step explanation:
-3x^2 + 2y^2 + 5xy - 2y +5x^2 - 3y^2
Combine like terms
-3x^2 + 5x^2 = 2x^2 2y^2 - 3y^2 = -1y^2
2x^2 - 1y^2 + 5xy - 2y
Now plug in the solutions Note: it is easier if you have all decimals or all fractions (-1/10=-.1
2(0.5)^2 - 1(-0.1)^2 + 5(0.5)(-0.1) - 2(-0.1)
Simplify:
0.5 - 0.01 - 0.25 + 0.2
0.5 + 0.2 - 0.01 - 0.25
0.7 - 0.26
0.44
