This is a basic subtracting problem.
$84.00 minus $29.00
Debit means it's been taken out of the bank account, so subtracted.
After subtracting the balance will be $55.00.
You can double check your work by adding 55 + 29 = 84.
Answer:
area = 3.44 in²
Step-by-step explanation:
area of square = 4 x 4 = 16 cm²
area of circle = (3.14)(2²) = 12.56 cm²
area = 16 - 12.56 = 3.44 in²
First blank: not random Because he sent it to the top 5 students. Not random students throughout the grade.
second blank: I would guess not valid because it was not a random sample.
2x - 1 + 3x + 6 = 90°
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85/5
x = 17°
Step-by-step explanation:
Here, f(x) is the given polynomial.
By remainder Theorem,
When divided by (3x-1),
f(1/3) = -3........(1)
When divided by (x+1),
f(-1) = -7.........(2)
<em>Another</em><em> </em><em>polynomial</em><em> </em><em>is</em><em> </em><em>3</em><em>x</em><em>²</em><em>+</em><em>2</em><em>x</em><em>-</em><em>1</em>
Solving,
3x²+2x-1
= 3x²+3x-x-1
=3x(x+1)-(x+1)
=(3x-1)(x+1)
So
f(x) = (3x-1)(x+1)Qx + (ax+b)
For f(-1),
-7 = -a+b
b= a-7
For f(1/3),
-3 = a/3+b
or, -3 = a/3+a-7
or, 4×3 = 4a
or a = 3
Also, b = 3-7 =-4
Hence, remainder is (3x-4)
