Answer:kilogram of quarters
Step-by-step explanation:
because quarters equal 25 cents each and it’s a kilogram
The first thing you would do is simplify the inside of the parenthesis to 55/6 using PEMDAS. Next all you do is multiply that by 5 to get 275/6 or 45.833 (repeating) in decimal form.
Answer:
y=14
Step-by-step explanation:
8-4/3-1= 2
so our m=2
now plug it in
4 = 2(1)+b
4 = 2+b
2=b
so it will be
y= 2x+2
y=2(6)+2
y=14
The factoring method which can be considered for such a cubic tetranomial expression is; factor by grouping sum of cubes.
<h3>What factoring method can be considered for the polynomial?</h3>
It follows from the task content that the order of the Polynomial is 3 and the polynomial is a tetranomial as it contains 4 terms.
On this note, since 3x³ is not a perfect cube, it follows that the best factorisation method for such a polynomial is; factor by grouping sum of cubes.

Answer:
Solve by factoring.
1. 2x^2+9x+26=-4x+5
2x²+9x+4x+26-5=0
2x²+13x+21=0
doing middle term factorization
2x²+7x+6x+21=0
x(2x+7)+3(2x+7)=0
<u>(</u><u>2</u><u>x</u><u>+</u><u>7</u><u>)</u><u>(</u><u>x</u><u>+</u><u>3</u><u>)</u><u>=</u><u>0</u>
<u>either</u>
<u>x</u><u>=</u><u>-</u><u>7</u><u>/</u><u>2</u>
<u>or</u>
<u>x</u><u>=</u><u>-</u><u>3</u><u>.</u>
2.
3x^2-6x-4=0
comparing above equation with ax²+bx+c=0
we get
a=3
b=-6
c=-4
By using quadratic equation
x=
Substituting value
x=
x=
x=
-8x=6±2√21
taking positive
-8x=6+2√21
x=
x=-
taking negative
-8x=6-2√21
x=
x=-
