I can help you only with #2.
Area= l*w
Area=(l+3)*w
Area= 130
Let's try 10 and 13.
Is the length 3 greater than its width? YES
Does it multiply to 130? YES
LENGTH= 13 CM
WIDTH=10 CM
cHECK=
13*10=130
Answer:
3/x^2 or 3x^-2
54x^5
x^-1/3
Step-by-step explanation:
2 6x^3×9x^2=54x^3+2=54x^5
3 x^2/3 × x^-1=x^-1/3
52 °
add up 38+90
128
180-128= 52 and there’s your answer
Y = -1/3x + 2
Explain: subtract 3x from 18, which will get you -3x + 18.
Next, get 9y and divide it by everything so it’ll look like 9y = -3x + 18
-——-————
9y
and you’ll get y = -1/3x + 2
Hope this helped
Answer:
2x-10+x+x+10=180, or 4x=180
Step-by-step explanation:
So since the total is 180, you add them all up like an equation.
So,
2x-10+x+x+10
Combine like terms
4x=180
x=45
Then plug it back in to the equations.
x=45
(2x-10)=80
(x+10)=55
