The correct answer is:  [D]:  " \frac{5a + 7b}{3} " .
__________________________________________________
Explanation:
__________________________________________________
\frac{b(5a + 7b)}{b +2b} ; 

Simplify the "denominator" ;   →  (b + 2b = 1b + 2b = 3b) ; 

 and rewrite: 

\frac{b(5a + 7b)}{3b} ; 

Cancel out the "b" in the "numerator" to a "1" ; 
              and cancel the "3b" in the "denominator to a "3" ; 

{since:  "b ÷ b = 1 ";  and since:  "3b ÷ b = 3" } ;

and rewrite as:
____________________________________________________
            \frac{5a + 7b}{3} ; 
____________________________________________________

   →  which is:  Answer choice:  [D]:  "  \frac{5a + 7b}{3} " .

What shapes are formed by cross sections parallel to the base of a hexagonal pyramid?
siniylev [52]

The answer is the option B, which is: B. Similar hexagons.

The explanation for this answer is shown below:

By definition, a cross section is the shape that is formed when a plane cuts or makes a slice through a solid.

The hexagonal pyramid has an hexagonal as its base. If you make slices parallel to the base of this pyramid, you will see the shape of this base in different sizes. Therefore the shapes that are formed by cross sections parallel to the base of the hexagonal pyramid are similar hexagons.

Marking brainliest for a simple math problem​
nalin [4]

Answer:

B. 88

Step-by-step explanation:

a6 = 87, a7 = 89

so, the median = (87+89)/2 = 88

3. Use trigonometric ratios to solve for the variable. Show your work. Round lengths to the nearest tenth and angles to the near
Lynna [10]

Answer:

x = 3.4

Step-by-step explanation:

recall that for a right angle with an internal angle θ,

cos θ = adjacent length / hypotenuse

in our case,

θ = 55 deg

adjacent length = x units

hypotenuse = 6 units

substitute these into the formula above

cos θ = adjacent length / hypotenuse

cos 55 = x / 6    (multiply both sides by 6)

x = 6 cos 55 (use calculator)

x = 3.4415

x = 3.4  (rounded to nearest tenth)
