Answer:
length = 9, width = 7
Step-by-step explanation:
length = l, also w+2 width = w
perimeter = 2w + 2l
create an equation: 32 = 2(w) + 2(w+2)
simplify
32 = 2w+2w+4
32 = 4w+4
28=4w
w=7
solve for length
l = w+2
l=7+2
l=9
Given :-
- a² - 2a - b² = 0
- 2b + 2ab = 0
To find :-
Solution :-
<u>Taking</u><u> </u><u>second</u><u> </u><u>equation</u><u>:</u><u>-</u>
- 2b + 2ab = 0
- 2b ( 1 + a ) = 0
- 2b = 0 or (1+a) = 0
- b = 0 , a = -1
<u>Substitute</u><u> </u><u>in </u><u>first </u><u>equation</u><u> </u><u>:</u><u>-</u><u> </u>
<u>When </u><u>b </u><u>=</u><u> </u><u>0</u><u> </u><u>,</u>
- a² - 2a - 0² = 0
- a² - a = 0
- a( a -1) =0
- a = 0 , 1
<u>When </u><u>a </u><u>=</u><u> </u><u>-</u><u>1</u><u> </u><u>,</u>
- (-1)² - 2*(-1) - b² = 0
- 1 + 2 - b² = 0
- b² = 3
- b = ±√3
<u>Answer </u><u>:</u><u>-</u><u> </u>
- a = 0,1 ; b = 0
- a = -1 , b = ±√3
i will solve it first i need full form
Sample space is (3FD , 3MD, 4MN, 6FN)
where F=female M= male N=Nurse D=doctor)
so P(doctor or female ) = (3+3+6) / 16 = 12/16 answer
Its C
Answer:
Any equation of the form
y = kx + b,
with b different from zero
Step-by-step explanation:
For example
y = 5*x +3
cannot be written in the form
y = k*x, because there is a term that shifts the graph upwards.
