So, when adding in the 7 and 3 the new equation is:
9{(9x7)+(4x3)+9}
Following pemdas, you have to do parenthesis first. So now the equation is:
9(63+12+9)
Now distribute the 9:
567 + 108 + 81
And finally solve as a normal addition problem:
567 + 108 + 81= 756
So, the answer is 756.
I hope this helps:)
Answer:
x = - 2, x = 7
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
x² - 5x - 14 = 0 ← in standard form
(x - 7)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 2 = 0 ⇒ x = - 2
Answer: I think it is 1572 sq feet
Step-by-step explanation:
Lxwxh
14x13x9=1638
Window is 4x4.5=18
Door 1 is8x3=24
Door 2 8x3=24
Since the doors and window are not included in what was painted you need to subtract those totals from the room.
So, 1638-18=1620
1620-48(two doors)=1572 sq feet
