(2x+y)^ - (x-2y)^

(2x+y)(2x+y) - (x-2y)(x-2y)

4x^ + 2xy + 2xy + y^ - x^ + 2xy + 2xy - 4y^

3x^ - 3y^ + 8xy , I believe ! I'm not 100% on this one though, sorry,!!

(^ is ^2 !!)

Megan and Heidi are making cookies for an upcoming bake sale. Megan is making chocolate chip cookies and Heidi is making sugar c

koban [17]

Answer:

Heidi (260 cookies)

Step-by-step explanation:

Megan's equation is given as y=8x, where x is the number of bags, and y the number of cookies:

#First calculate Heidi's total number of bags, cookies and cookies:

$H_b=\sum{bags}\\\\=10+12+14+16\\\\=52 \ bags\\\\H_c=\sum{cookies}\\\\=50+60+70+80\\\\=260 \ cookies$

#Given that both Heidi and Megan make the same number of bags of cookies, Megan's cookies totals to:

$H_b=M_B=52 \ Bags\\\\M_c=y=8x, x=52\\\\y=8\times 52\\\\=416\\$

Hence, Megan makes 416 cookies.

#From our calculations:

$416>260\\\\M_c>H_c$

Hence, Heidi makes the least number of cookies(260 cookies) compared to Megan's 416 cookies.

4 + 6x + 5 = 7x Could someone help me? Thanks :) And could you also show how u did it

matrenka [14]

Answer:

x=9

Step-by-step explanation:

combine like terms

$4+6x+5=7x$

4+5=9

9+6x=7x

to get 6x with 7x subtract 6x from both sides as its positive

6x-6x=0

7x-6x=x

9=x

x=9

Completely factor each of the given polynomials. If a polynomial cannot be factored, write "not factorable."

Art [367]

4x^2+23x+15=0
Δ=23^2-4*4*15=529-240=289

x1= (-23+17)/8=-6/8= -3/4
x2= (-23-17)/8=-5

4x^2+23x+15= 4(x+3/4)(x+5)=(4x+3)(x+5)

What is the answer to this problem?

aivan3 [116]

X = 6, y = 8, z = 3
$\frac{3y + x^{2} }{z}$
3(8) + (6)² = 24 + 36 = 60
$\frac{60}{3}$ = 20
