Answer:
1. 4(p - 7) = 44
4p - 28 = 44
Need to move 28 to the other side so we have 4p= ...
4p = 44 + 28
4p = 72
4p/ = 72/4
p = 18
2.
3. Simplify 30% to 0.30 and after multiply by 42 so you will get 12.6 and then simplify 25%, and you get 10.5 and after you will add it to $42.00 and you will get $65.10 which is you answer
1+1= 2
2/2= 1 is the answer
Any number divided by itself, such as two divided by two, is one. :)
Answer:
the value of x is 88
Step-by-step explanation:
plz see and check
<span>f(x) =-(x+9)(x-21)
Manipulating algebrically,
We get,
</span>f(x) =-(x+9)(x-21)
= -(x^2 -21x + 9x - 189)
= -(x^2 -12x - 189)
= -x^2 + 12x + 189
Axis of symmetry = -b/2a
plugging the values,
x = -12/-2
= 6
