Hope this helps. :)
Answer:
2.50
Step-by-step explanation:
If 4= $5.00
then divided 5.00 by 4=1.25
so 1 = 1.25
1.25x2=2.50
Therefore 2 tastykake snack cakes = $2.50
F(x)=x^2+2x+1 & g(x)=3(x+1)^2
now, f(x)+g(x)
=x^2+2x+1+3(x+1)^2
=x^2+2x+1+3(x^2+2x+1)
=x^2+2x+1+3x^2+6x+3
=4x^2+8x+4<===answer(c)
next:
f(x)=x^2-1 & g(x)=x+3
now, f(g(x))=(x+3)^ -1
=x^2+6x+9-1
=x^2+6x+8<====answer(b)
i solve two of ur problems.
now try the 3rd one that is similar to no. 1
and try the last two urself.
Answer:
![m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o](https://tex.z-dn.net/?f=m%5Cangle%20a%3D48%5Eo%5C%5Cm%5Cangle%20b%3D82%5Eo%5C%5Cm%5Cangle%20c%3D50%5Eo)
Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
![m\angle a+m\angle b+m\angle c=180^o](https://tex.z-dn.net/?f=m%5Cangle%20a%2Bm%5Cangle%20b%2Bm%5Cangle%20c%3D180%5Eo)
substitute the given values
![4x^o+(7x-2)^o+(5x-10)^o=180^o](https://tex.z-dn.net/?f=4x%5Eo%2B%287x-2%29%5Eo%2B%285x-10%29%5Eo%3D180%5Eo)
solve for x
![(16x-12)^o=180^o](https://tex.z-dn.net/?f=%2816x-12%29%5Eo%3D180%5Eo)
![16x=180+12\\16x=192\\x=12](https://tex.z-dn.net/?f=16x%3D180%2B12%5C%5C16x%3D192%5C%5Cx%3D12)
Find the angle measurements
![m\angle a=4(12)=48^o](https://tex.z-dn.net/?f=m%5Cangle%20a%3D4%2812%29%3D48%5Eo)
![m\angle b=7(12)-2=82^o](https://tex.z-dn.net/?f=m%5Cangle%20b%3D7%2812%29-2%3D82%5Eo)
![m\angle c=5(12)-10)=50^o](https://tex.z-dn.net/?f=m%5Cangle%20c%3D5%2812%29-10%29%3D50%5Eo)
