Answer:
-2 < x<4
Step-by-step explanation:
We have open circles and -2 and 4 so we don't include those numbers
The line is in between so the x is in between
-2 < x<4
SA = 2<span>(<span><span><span>wl</span>+<span>hl</span></span>+<span>hw</span></span><span>)
SA = </span></span>2<span>(<span><span><span>(3)(10)</span>+<span>(8)(10)</span></span>+<span>(8)(3)</span></span><span>)
Multiply:
SA = 2(30 + 80 + 24)
Add:
SA = 2(134)
Multiply:
SA = 268</span></span>
Answer:
x ≈ 3.29
Step-by-step explanation:
Take the logarithm of both sides of the equation to remove the variable from the exponent.
Exact Form:
x = 
Decimal Form:
x = 3.29202967
… ≈ 3.29 (Round to what the question asks, in this case, I rounded to 2 decimal places)

Standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.
