Answer:

-28y^4 - 7y^3 + 62y^2 + 5y - 30

Step-by-step explanation:

Opening the parenthesis and simplifying by combining like terms:

(6 - y - 4y^2)(-5 + 7y^2) =
6(-5) +6(7y^2) - y(-5) -y(7y^2) -4y^2(-5) -4y^2(7y^2) =
-30 + 42y^2 + 5y - 7y^3 +20y^2 -28y^4 =
-28y^4 - 7y^3 + 62y^2 + 5y - 30

The height if a pyramid is the perpendicular distance between the base and the top of the pyramid. Which is greater, the height

kvasek [131]

The slant would be greater than the height because it is the hypotenuse and it is always greater than the legs.

Hope this helps

The model below represents the equation 3x+2=2x-5,

Leno4ka [110]

Step-by-step explanation:

Hey there!

The equation is;

$3x + 2 = 2x - 5$

Shifting "2x" to left side and "2" to right side.

$3x - 2x = - 5 - 2$

Simplify them to get answer.

$x = - 7$

Therefore the value of x is -7.

Check;

3 × -7 + 2 = 2 × -7 -5

-19 = -19 ( True ).

So, your answer is option B.

Hope it helps..

You have a wire that is 38 cm long. you wish to cut it into two pieces. one piece will be bent into the shape of a square. the o

erica [24]

Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2 $\pi$ r=x
r= $\frac{x}{2 \pi }$
Area= $\pi$ r^2
so..
A= $\pi$ ( $\frac{x}{2 \pi }$ )^2
= $\pi$ ( $\frac{x^{2} }{4 \pi ^{2} }$ )
= $\frac{x^{2} }{4 \pi }$

(38-x) is perimeter
then
$\frac{38-x}{4}$
( $\frac{38-x}{4}$ )^2
$\frac{x^{2} }{4 \pi }$ + ( $\frac{38-x}{4}$ )^2
then you graph it and it equals
16.716 cm the circumference of the circle

I need help understanding this. SO please help and give explanation

NikAS [45]

So my understanding from this you have to make it y = mx + b so m stands for the slope there’s different ways to find it as shown in the first picture. I’ll try to make another comment since this only lets me take one picture at a time.
