What is 6x(13-6) =7 squared?

2 answers:

6 0

The first step is to multiply the "6X" by what is inside the brackets. This gives you 78X - 36X = 7²

7²= 7X7 = 49

Next simplify the equation 78X-36X= 42X
So 42X = 49
Divide both sides by 42 to get X= 1.1666666...

(The 6 is recurring)

6 × (13 - 6) = 42, not 7, but 7² is 49 and 42² is 1,764.
I hope this helps!

What is the volume of a rectangular prism with the dimensions: base 3 1 2 cm, height 1 1 2 cm, and length 5 1 2 cm?

jenyasd209 [6]

Answer:

The volume of a rectangular prism is $28\frac{7}{8}\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the rectangular prism is equal to

$V=BHL$

Convert the given dimensions to an improper fractions

$B=3\frac{1}{2}\ cm=\frac{3*2+1}{2}=\frac{7}{2}\ cm$

$H=1\frac{1}{2}\ cm=\frac{1*2+1}{2}=\frac{3}{2}\ cm$

$L=5\frac{1}{2}\ cm=\frac{5*2+1}{2}=\frac{11}{2}\ cm$

substitute in the formula

$V=(\frac{7}{2})(\frac{3}{2})(\frac{11}{2})=\frac{231}{8}\ cm^{3}$

Convert to mixed number

$\frac{231}{8}=\frac{224}{8}+\frac{7}{8}=28\frac{7}{8}\ cm^{3}$
