Which expression would be equivalent to: Which expression would be equivalent to: \frac{1+b}{2} - 3(a-1)

IrinaVladis [17]

Answer:

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Step-by-step explanation:

Given

$\frac{1+b}{2} - 3(a-1)$

Required

An equivalent expression

$\frac{1+b}{2} - 3(a-1)$

Take LCM

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 2*3(a-1)}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6(a-1)}{2}$

Open bracket

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6a+6}{2}$

Collect like terms

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+6+1}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Hence, an equivalent expression is:

$\frac{b- 6a+7}{2}$

Please help me on dis question

lara [203]

Answer:

a) See below

b) $\huge\boxed{\sf Area\ of\ each\ triangle = 62.4\ in.\²}$

c) $\huge\boxed{\sf Area\ of\ the\ table = 374.4\ in.\²}$

Step-by-step explanation:

We can draw 3 lines from A to D, B to E and F to C such that all of the lines pass from the center. This will form 6 equal (congruent) triangles.

$\rule[225]{225}{2}$

Area of each triangle = 1/2 (Base)(Height)

Where Base = 12 in. and Height = 10.4 in.

Area = 1/2 (12) (10.4)

Area = 6 (10.4)

Area of each triangle = 62.4 in.²

$\rule[225]{225}{2}$

Since the table is mage up of 6 equal triangles:

So,

Area of the table = 6 (Area of each triangle)

Area of the table = 6 (62.4)

Area of the table = 374.4 in.²

$\rule[225]{225}{2}$

Hope this helped!
