So you're gonna take add 1 to both sides and add aw to both sides also
y+1=2w+aw
then you factorize the w
y+1=w(2+a)
divide 2+a in both sides
y+1/2+a=w
the answer is
y+1/2+a=w
X=17.3
but the 3 has a line above. which means repeated
Answer: The equation that goes through the points (2, -1) and (-6, -5) is 1/2x - 2
I know this because when I graphed this equation, it passed through those points. (My graph is shown below)
Answer:
-6
Step-by-step explanation:

input the numbers

do the problem in the parentheses first
-6-12 = -18
now it becomes

simplify and you'll get
-6
this is because -18 ÷ 3 =
-6
Answer:
222.7 cm³ of paper to wrap this.
Step-by-step explanation:
The rectangular prism is SA=2(wl+hl+hw)
Where:
w=5 l=5 h=4
SA= 2((5*5)+(4*5)+(4*5))
SA=2(25+20+20)
SA=2(65)=130cm³
The square base pyramid is 

≈92.69578 cm³
Add the two together 130+92.70 =222.7 cm³
