Answer:
Step-by-step explanation:
132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have 540 degrees. Remove the brackets.
132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540 Collect like terms
13x + 241 = 540 Subtract 241 from both sides.
13x = 540 - 241
13x = 299 Divide by 13
x = 299/13
x = 23
<P = 4x + 2
<P = 92 + 2
<P = 94
Bob is x yrs old
Sister is x+6 yrs old
X+X+6=32
2X+6=32
2X=32-6
2X=26
2X/2=26/2
X=13
Bob is 13 yrs old
Sister is 13+6 yrs
= 19 yrs
13yrs+19yrs = 32 yrs
Now its 100% accurate
Answer:
(d) x = 3 or x = 4
Step-by-step explanation:
The zero product property can be used to find the solutions to a polynomial equation when it is written in factored form.
__
Your polynomial can be put in factored form like this:
x² +12 = 7x . . . . . given
x² -7x +12 = 0 . . . . . standard form
(x -3)(x -4) = 0 . . . . . factored form*
x = 3 or x = 4 . . . . . . values of x that make the factors zero
_____
* The constants in the binomial factors must have a sum of -7 and a product of +12. It is often convenient to find them by listing factor pairs of 12:
12 = (-1)(-12) = (-2)(-6) = (-3)(-4)
Negative factors are used because we know the sum must be negative. Both have the same sign so their product is positive. The sums of the pairs shown are -13, -8, -7. The last pair is what we're looking for.
Answer:
<h2>Independent variable: Weight of Onions.</h2><h2>Dependent variable: Total Cost.</h2>
Step-by-step explanation:
The given table is about the weight of onions in pounds and the total cost.
If you think this through, you would notice that the total cost depends on the number of pounds of onions. That means the independent variable is Weight of Onions and the dependent variable is the Total Cost.
So, to put it in a sentence: The weight of onions determines the total cost.
