What is the value of 6(2b-4) when b =5

Sindrei [870]

Answer: The value of $6(2b-4)$ is 36.

Step-by-step explanation:

Given expression: $6(2b-4)$

To find the value of $6(2b-4)$ at b= 5, we need to substitute the b=5 in the expression, we get

$6(2(5)-4)\\=6(10-4).......[\text{solve parentheses}]\\=6(6)\\=6\times6=36$

$\\\Rightarrow6(2(5)-4)=36$

Therefore, the value of $6(2b-4)$ is 36, when b=5.

Find the area. The figure is not drawn to scale

poizon [28]

Answer:

96 square inches.

Step-by-step explanation:

From given picture we see that

BC=8 in

AD=10 in

Given that

AD=AB

Then AB=10 in

Apply Pythagorean theorem in triangle ABC to find AC

$(hypotenuse)^2=(base)^2+(perpendicular)^2$

$(AB)^2=(BC)^2+(AC)^2$

$(10)^2=(8)^2+(AC)^2$

$100=64+(AC)^2$

$100-64=(AC)^2$

$36=(AC)^2$

take square root

$6=AC$

Then area of triangle ABC $=\frac{1}{2}\left(base\right)\left(altitude\right)$

$=\frac{1}{2}\left(8\right)\left(6\right)=24$

There are total 4 congruent triangles.

Then total area of the given figure = 4(24)=96 square inches.

Factor the expression 2x4y – 18x2y3 completely.

Annette [7]

Answer:

B. 2x2y(x – 3y)(x + 3y)

Step-by-step explanation:

$2 {x}^{4} y - 18 {x}^{2} {y}^{3} \\ = 2 {x}^{2} y( {x}^{2} - 9 {y}^{2} ) \\ = 2 {x}^{2} y \{ {x}^{2} - {(3y)}^{2} \} \\ \purple {\boxed{ \bold{ = 2 {x}^{2} y(x - 3y)(x + 3y)}}}$
