Answer:
- -24
- >
Step-by-step explanation:
1. You can use a calculator if your knowledge of arithmetic fails you.
... 98 +17 +37 -176 = 152 -176 = -24
___
2. -37/8 = -(32 +5)/8 = -4 5/8 = -4.625
This number is on the left side of zero on the number line, but is slightly closer to zero than -4.63, so is "greater than" -4.63.

Answer:
x = - 5, x = 2
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log ( )
x = n ⇔ x =
note that log x = x
Given
log (x² + 3x) - log10 = 0, then
log( ) = 0, thus
=
= 1 ( multiply both sides by 10 )
x² + 3x = 10 ( subtract 10 from both sides )
x² + 3x - 10 = 0 ← in standard form
(x + 5)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 2 = 0 ⇒ x = 2
Solution is x = - 5, x = 2
