Answer:

First x=-2

Second x= -11.94

Step-by-step explanation:

1 |2x-3|+5=4

2x+3+5=4

2x+8=4

2x=-4

Divide by 2 for both parties

X = -2

Number 2

215x +31-10=3

215x+21=3

215x= -18

Divide by 215 on both sides

X= - 11.94

A square has a side length of 14 inches. This square is dilated by a scale factor of 35 to create a new square. What is the side

Harman [31]

The new side length is 8.4. When you do dialations, you multiply the side length, 14, by the scale factor, 3/5. 14 × 3.5 gives you the answer 8.4. Hope this helps!

If f(x) = 2x^3 + Ax^2 +4x -5 and f(2)=5, then what is the value of A?

galina1969 [7]

Answer:

$\dfrac{-7}{2}$

Step-by-step explanation:

Here we are given a polynomial ,

$\implies f(x) = 2x^3 + Ax^2 + 4x - 5$

And the value of ,

$\implies f(2) = 5 \dots (i)$

And we need to find out the value of A . Firstly substitute x = 2 in f(x) , we have ,

$\implies f(2) = 2(2)^3+ A(2)^2 + 4(2) -5$

Simplify the exponents ,

$\implies f(2) = 2(8) + A(4) + 8 - 5$

Simplify by multiplying ,

$\implies f(2) = 16 + 4A + 3$

Add the constants ,

$\implies f(2) = 19 + 4A$

Now from equation (i) , we have ,

$\implies 19 + 4A = 5$

Subtracting 19 both sides,

$\implies 4A = 5-19$

Simplify,

$\implies 4A = -14$

Divide both sides by 4 ,

$\implies A =\dfrac{-14}{4}=\boxed{ \dfrac{-7}{2}}$

Hence the value of A is -7/2.

yan [13]

Answer:

If I understand this right, the answer is $48.00

Step-by-step explanation:

If they pay $1.50 three times a month just times $1.50 by 12 because there are 12 days in a month, then you get 16, then you times 16 by 3 and you get 48.

What are the lengths of sides A and B of a right triangle if the hypotenuse is equal to 1.2 cm and the interior angles are 60 de

Natali5045456 [20]

We have been given that the hypotenuse of a right triangle is equal to 1.2 cm and the interior angles are 60 degrees, 30 degrees, and 90 degrees.

We know that hypotenuse corresponds to 90 degrees angles.

We also know that the hypotenuse is equal to twice the length of the shorter leg and shorter leg is the opposite side to 30 degree angle.

To find the length of shorter leg, we will divide length of hypotenuse by 2.

$\text{Side corresponding to 30 degree angle}=\frac{1.2\text{ cm}}{2}$
