the town of lantana needs 14,000 for a new playground. Lantana elementary school raised 5,358, Lantana middle school raised 2,83

Alecsey [184]

Assuming the question is "how much more money needs to be raised..."

Add the contributions:

5,358 + 2,834 + 4,132 = 12,324 < this is the current total amount raised. subtract this from the goal, 14,000 to find out much more money is needed for the playground.

14,000 - 12,324 = 1,676

Answer: $1,676 is still needed in order to create the playground.

3*20= 60

Help on number 12 please?

zloy xaker [14]

Answer:

f(n)= 5 · 4

$f(n) = 5 \times 4 ^{n - 1}$

Step-by-step explanation:

You use the explicit formula for geometric sequence. The five is the firat term and is placed correctly. The 4 is the rate of change, because if you multiply 5 by 4 you get 20 and so on.

Factoring Trinomials

alexandr402 [8]

25 a² + 20 ab + 4 b²

for formula $a^x+bx^ky^k+cy ^{2k }$ find u,v such that: u.v = a

and u+v = b then group according to $(ax ^{2k} +ux^ky^k)+(vx^ky^k+cy ^{2k} )$

= $(25a^2+10ab)+(10ab+4b^2)$

factor out 5a from : $25a^2+10ab : 5a(2b+5a)$

factor out 2b from : $10ab+4b^2: 2b(2b+5a)$

= $5a(2b+5a) + 2b(2b+5a)$

factor out : $(5a+2b)$

= $(5a+2b)(5a+2b)$

Refine:

$(2b+5a)^2$

hope this helps!.
