So, the truck is 92 grams heavier.
1) first step
you must do( a+b) ^2 = a^2+2ab+b^2
then
2)second step
y = -3(x+1)^2 +4 = -3( x^2+2x+1) +4⇒ y = -3x^2-6x-3 +4, y = 3x^2-6x+1
now the graph of this function is
Answer:
1800in
Step-by-step explanation:
3ft=1yd
3x50=150ft
12in=1ft
12x150=1800in
You can set this up as a proportion.
6/2.7=x/11.4
Cross multiply.
2.7x=68.4
Divide by 2.7 to solve for x
25.3333=x
The tree is 25 and 1/3 feet tall
