<u><em>Answer: x=-25 and -25=x *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
multiply by -5 both sides of an equation.
(-2/5x)(-5)=10(-5)
simplify by equation.
2x=-50
divide by 2 both sides of an equation.
2x/2=-50/2
simplify by equation.
50/2=25
25*2=50
50/25=2
It changes positive to negative.
x=-25 and -25=x
Hope this helps!
Thanks!
Have a great day!
(g₀f)(x)=g(f(x))
=g(2x-2)
=5(2x-2)^2-3
=5(4x^2-8x+4)-3

Answer: 2 enlargments
Step-by-step explanation:
Use proportion for each enlargment you do
Side a=6cm Side b=4cm
6:4=x:7 4:4=b1:7
7*6=4a1 b1=28/4
a1=42/4 b1=7 after first enlrge
a1=10.5 after first enlarge 7:4=b2:7
10.5:4=a2:7 b2=49/4
a2=73.5/4 xb2=12.5 after 2nd enlarge
a2=18.375 after 2nd enlarge
12.5:4=b3:7
18,375:4=a3:7 b3=21.875 cm after 3rd enlargement
a3=32.15after 3rd enlargement
Values after 3rd enlargement are higher than dimension given for picture wall
30 cm by 20 cm
Answer:
90
Step-by-step explanation:
720 divide by 8
then times it by 1
