Answer:
on what
Step-by-step explanation:
??????
First one,
12q^2+34q-28
divide whole thing by 2
6q^2+17q-14
use trial and error and get (2x+7)(3x-2)
factored out form is (2)(2x+7)(3x-2)
2.
divide by 3
6h^2+5h-6
trial and error and get (2x+3)(3x-2)
so the factored form is (3)(2x+2)(3x-2)
3. divide by 2
6p^2-11x-10
use trial and error and get (2x-5)(3x+2)
the factored out form is (2)(2x-5)(3x+2)
4.divide by 4
2z^2+5z-12
use trial and error and get (x+4)(2x-3)
the factored form is (4)(x+4)(2x-3)
to factor the basic thing is
ax^2+bx+c
b=x+y
ac=xy
solve for x and y
so exg 2z^2+5z-12
a=2
b=5
c=-12
2 times -12=-24
then factctor -24 and find factors that add up to 5
-1, 24
-2, 12
-3, 8
-4,6
now add
-1+24=23
-2+12=10
-3+8=5 check
-4+6=2
the numbers are -3 and 8
split it into such
2z^2+8z-3z-12
group (2z^2+8z)+(-3z-12)
undistribute using distributive property
ab+ac=a(b+c)
(2z)(z+4)+(-3)(z+4)
now reverse distribute again
((2z)+(-3))(z+4)
(2z-3)(z+4)
Answer:
From the figure, we´ll use the ratio of sin74
sin74=x/16
x=16/sin74
x=16.64
OAmalOHopeO
2b/4=8 multiply both sides by 4
2b=32 divide both sides by 2
b=16
So Julia has 16 barrettes.
Answer:
32 percent the puppy's weighed increased.
Step-by-step explanation:
In February Lana got a puppy that weighed 13 kilograms.By October the puppy weighed 17.16 kilograms.
Original weighed = 13 kilogram
Final weighed = 17.16 kilogram.
Increase in weighed = 17.16-13 = 4.16 kilogram.
Now to find the percent the puppy's weighed increased.
Percent =
Percent =
Hence, the percent the puppy's weighed increased was 32%.
