vlabodo [156]

Answer:

a, d, e

Step-by-step explanation:

#1  Multiply the two polynomials.

(2x+3)(5x^2+3x+2)=(2x)(5x^2)+(2x)(3x)+(2x)(2)+(3)(5x^2)+(3)(3x)+(3)(2)\\=10x^3+6x^2+4x+15x^2+9x+6\\=10x^3+21x^2+13x+6

#2

(3y+4)(2y^2+5y-3)=(3y)(2y^2)+(3y)(5y)-(3y)(3)+(4)(2y^2)+(4)(5y)-(4)(3)\\=6y^3+15y^2-9y+8y^2+20y-12\\=6y^3+23y^2+11y-12

cara is making a beaded necklace for a gift. she wants to spend more than $25 because she doesn´t want to seem like a cheap frie
snow_tiger [21]

Answer:

5 small beads!

Step-by-step explanation:

Hey there!

If large beads are $3 each, and she buys 5 of them, our equation is $3 x 5 which equals $15. So Cara will spend $15 buying large beads.

Cara has $10 left now, because $25 - $15 = $10. Since each small bead is $2, we divide $10 (the total amount of money she has) by $2 (the cost of each bead). This will tell us how many she can buy! So $10 ÷ $2 is 5. Cara can buy 5 small beads!

I hope this helped you! Rating my answer and giving it a Thanks would sure help me out!

Have a wonderful day!

The points (6,8) and (5,5) fall on a particular line.
Doss [256]

Answer:

y=3x-10

Step-by-step explanation:

To find equation of the line passing through points

and A(xa, ya) and B(xb, yb)

, we use formula: y-ya = yb-ya/xb-xa (x-xa)

In this example we have xa=

6 ,ya=

8 , xb=5

and yb=5

. So,

y-ya= yb-ya / xb-xa (x-xa)

y-8 = 5-8/ 5-6 (x-6)

y-8= 3(x-6)

y-8= 3x-18

y-8= 3x-10

y = 3x - 10
