Answer:

a=3\text{ and } b=-17

Step-by-step explanation:

We are given that:

5x^2+bx-12=(5x+a)(x-4)

First, we can distribute the right-hand side:

5x(x-4)+a(x-4)

Distribute:

=5x^2-20x+ax-4a

Rewrite:

=5x^2+(-20+a)x-(4a)

Since it is equivalent to the above expression, the coefficients of the variables must match. This means that:

-20+a=b\text{ and } 12=4a

Solving for a in the second equation gives:

a=3

Therefore:

b=-20+3=-17

Mia hired a moving company. The company charged \$500$500dollar sign, 500 for its services, and Mia gives the movers a 16\%16%16
Tamiku [17]

Answer:

Consider the complete question is,

'Mia hired a moving company. The company charged $500 dollar sign, 500 for its services, and Mia gives the movers a 16%, percent tip. How much does Mia tip the movers?'

Reference : brainly.com/question/11225910

Solution :

The original amount charged = $ 500,

Percentage of tip = 16%,

Thus, the amount of tip = 16% of the original charge

= 16% of 500

=\frac{16\times 500}{100}

=\frac{8000}{100}

= $ 80

Hence, Mia gave $ 80 tip to the movers.

Find the area of a regular polygon
Law Incorporation [45]

Answer: Area of the polygon is 43.31 cm^2 t

Step-by-step explanation:

The polygon show in the diagram is a hexagon. It has six sides, since it is a regular hexagon, all the six sides are equal.

From the information given, the apotherm = 5√3

The apotherm is the perpendicular distance from the center of one side of the polygon to the center of the polygon. To determine the area of the polygon,

Area of polygon

=area = a^2n ×tan 180/n

Area = (5√3)^2 tan(180/6)

Area = 5^2×(√3)^2 × tan30

Area = 25×3×0.5774

Area = 43.305

Approximately 43.31 cm^2 to the nearest tenth
