x^2 + y^2 = 25 -2 + y =3
25 - 2 +y = 3
23 + y =3
y =3 -23
y = - 20
x^2 +y^2 =3
x^2 +(-20)^2 = 3
x^2 +400 =3
x^2 =3-400
x^2 =-397
x = -397
x =square root of (-397)
we can solve this by using the science calculator.
so thath answer is 19.9248588452
9/10x =1/2x +12
9/10x -1/2x= 12
(9x-5x)/10 = 12
4x/10 =12
4x =120
x =120/4
x = 30
that is the value of x
2 -15(-x +1) = 3 +2(5 -x)
2 +15x - 15 = 3 +10 -2x
15x -13 = 13 - 2x
17x = 26
x = 26/17
=
(7x -4)(3x +9)
21x^2 -63x -12x +36
21x^2 -75x +36
that is the multipy of (7x-4)(3x + 9)
1/4 *3/1
=1/4 *3
=3/4
this is the answer dr......
Now we use the calculator to solve this quickly.
12556/632
=19.8670886075949367
then short the answer for 2 decimal nums.
so that answer is 19.87//
-(3 + p) (-p)
-(-3p - p^2)
3p +p^2
56 -8[(5 +40 -12)/20]
56 -8(33/20)
56 -66/5
(280 - 66)/5
114/5
22.8//
I think this is a simpy quiz. but are sure that quiz is true?????????????
4x + 3 +5x +y
4x +5x +y +3
9x +y + 3 this is the answer for ur easy quiz......
(x+9)/3 = 8
(x+9) = 8*3
(x+9) = 24
x = 24 -9
x = 15
x =15 .It is the answer for x
+752
