We need to find the surface area and volume for each rectangular prism. Here are the formulas I'm going to plug each prism's measurements.
S.Area=2(lw+wh+lh)
Volume: lwh

Question 75:
Volume: 3×1×3=9 cm³
Surface Area= 2(3)+2(3)+2(9)=6+6+18=30 cm²

Question 76:
Volume: 6×2×5=60 ft.³
Surface Area: 2(12)+2(10)+2(30)=24+20+60=104 ft²

Question 77:
Volume: 4×2×6=48 m³
Surface Area: 2(8)+2(12)+2(24)=16+24+48=88 m²

What is 3 log Subscript 2 Baseline x minus (log Subscript 2 Baseline 3 minus log Subscript 2 Baseline (x + 4)) written as a sing

Serhud [2]

Answer:

$\log_{2} [\frac{x^{3}(x + 4)}{3}]$

Step-by-step explanation:

We have to write the following logarithmic expression as a single logarithm.

The given expression is

$3\log_{2} x - [\log_{2} 3 - \log_{2}(x + 4)]$

= $3\log_{2} x - \log_{2} (\frac{3}{x + 4})$

{Since, $\log A - \log B = \log \frac{A}{B}$ , from the properties of logarithmic function }

= $\log_{2} x^{3} - \log_{2} (\frac{3}{x + 4})$

{Since, $a\log b = \log b^{a}$ , which also a logarithmic property}

= $\log_{2} [\frac{x^{3}}{\frac{3}{x + 4}}]$

= $\log_{2} [\frac{x^{3}(x + 4)}{3}]$ (Answer)
