What number is represented by 4x²+17x+2 if x=10?

Fynjy0 [20]

Answer:

at x = 10, $4x^{2} + 17x + 2 = 572$

Step-by-step explanation:

The given equation is $4x^{2} + 17x + 2$

Here, lets substitute the value of x = 10

So, the equation simplifies to ,

$4 \times (10)^{2} + 17(10) + 2$

= (4 x 100) + 170 + 2 = 400 + 170 + 2

= 572

So, at x = 10, $4x^{2} + 17x + 2 = 572$

A rectangular prism has a volume of 170 cubic centimeters. The length of the prism is 5 centimeters, and the height of the prism

luda_lava [24]

Answer:

The width of the prism is 2 cm

Step-by-step explanation:

The given parameters are;

The volume of the prism = 170 cm³

The length of the prism = 5 cm

The height of the prism = 17 cm

The volume of the prism is given by the relationship v = Length, l × Height, h × Width, w

Therefore;

The volume of the prism = 5 cm × 17 cm × w = 170 cm³

Which gives;

w = 170 cm³/(5 cm × 17 cm) = 170 cm³/(85 cm) = 2 cm

∴ The width of the prism = 2 cm.

Bella bought 3.2 meters of ribbon to decorate her pencil case. each meter cost $0.46. how much did the ribbon cost?

zlopas [31]

we know that

Each meter of ribbon cost $\$0.46$

by proportion

Find the cost of $3.2$ meters of ribbon

$\frac{0.46}{1} \frac{\$}{meter} =\frac{x}{3.2} \frac{\$}{meter} \\ \\x=3.2*0.46 \\ \\x=\$1.472$

therefore

the answer is

The ribbon cost $\$1.472$

kicyunya [14]

Answer:

The product is represented by Point A: -8.

Step-by-step explanation:

The expression is:

$X=(-4)(-2)(-1)$

Compute the value of X as follows:

$X=(-4)(-2)(-1)$

$=-4\times -2\times -1\\=-8$

Consider the number line given below.

The value of X is represented by the point A.

Thus, the product is represented by Point A: -8.
