∑ Hey, jillianwagler ⊃

Answer:

$\left(2x-1\right)\left(2x+5\right)$

Step-by-step explanation:

║Given info║:

Factor completely: $4x^2 +8x -5$

Solution~:

Breaking the expression~: $\left(4x^2-2x\right)+\left(10x-5\right)$

Factor out 2x from 4x² -2x : 2x(2x-1)

Factor out 5 from 10x - 5 : 5(2x - 1)

Put together: $=2x\left(2x-1\right)+5\left(2x-1\right)$

Factor out 2x - 1: $=\left(2x-1\right)\left(2x+5\right)$

The three angles of a triangle have

dexar [7]

Answer:

56°, 84°, 40°

Step-by-step explanation:

The three angles of triangles have measures of 56°, (2x + 4)º, and xº.

We need to find the measures of the three angles of the triangle.

We know that, the sum of angles of triangle is equal to 180º. Using this property we get :

56°+ (2x + 4)º + xº =180º

Solving for x.

60 + 3x = 180

3x = 120

x = 40º

Other angle, = 2x+4

= 2(40)+4

= 80+4

= 84º

So, the measures of the three angles of the triangle are 56°, 84°, 40°. Hence, the correct option is (c).

Allometric relations often can be modeled by f(x)= x^b, where a and b are constants. One study showed that for a male fiddler

dolphi86 [110]

Answer:

a) $f(2)= 0.448 (2)^{1.21}= 1.036 grams$

b) $0.5 = 0.448 x^{1.21}$

Dividing both sides by 0.448 we got:

$\frac{0.5}{0.448} = x^{1.21}$

We can appy the exponent $\frac{1}{1.21}$ in both sides of the equation and we got:

$(\frac{0.5}{0.448})^{\frac{1}{1.21}} = x= 1.095grams$

Step-by-step explanation:

For this case we know the following function:

$f(x) = 0.448 x^{1.21}$

The notation is: x is the weight of the crab in grams, and the output f(x) is the weight of the claws in grams.

Part a

For this case we just need to replace x = 2 gram in the function and we got:

$f(2)= 0.448 (2)^{1.21}= 1.036 grams$

Part b

For this case we know tha value for $f(x) =0.5$ and we want to find the value of x who satisfy this condition:

$0.5 = 0.448 x^{1.21}$

Dividing both sides by 0.448 we got:

$\frac{0.5}{0.448} = x^{1.21}$

We can appy the exponent $\frac{1}{1.21}$ in both sides of the equation and we got:

$(\frac{0.5}{0.448})^{\frac{1}{1.21}} = x= 1.095grams$

A menu has three meat choices,

wolverine [178]

Answer:

18 ways

Step-by-step explanation:

Number of Meat choices = 3

Number of Vegetable choices = 3

Number of Desserts = 2

Number of ways dinner can be chosen :

Number of meat choices * Number of vegetable choices * number of desserts

3 * 3 * 2

= 18

Hence, dinner can be chosen in 18 different choices.

A rectangular has sides that measure 9 centimeters by 12 centimeters by 23 centimeters. Joan filled the container to its brim wi

Svet_ta [14]

So you need to find the volume of the rectangular prism and the equation for that is V=l×w×h. If you plug those numbers in you'd get 9×12×23=2,484. If you multiply 2,484 by $\frac{1}{3}$ because you'd have to pour out $\frac{1}{3}$ of the water out so that it's only $\frac{2}{3}$ of the volume of water is left. 2,484× $\frac{1}{3}$ = 828mm.
