Answer:

$\large\boxed{7.\ B.\ 8s^2+16s+1}\\\\\boxed{8.\ D.\ -15t^9u^{11}}\\\\\boxed{11.\ C.\ 3,\ -2}$

Step-by-step explanation:

$7.\\(3s^2+7s+2)+(5s^2+9s-1)=3s^2+7s+2+5s^2+9s-1\\\\\text{combine like terms}\\\\=(3s^2+5s^2)+(7s+9s)+(2-1)\\\\=8s^2+16s+1$

$8.\\(-3t^2u^3)(5t^7u^8)=(-3\cdot5)(t^2t^7)(u^3u^8)\qquad\text{use}\ a^na^m=a^{n+m}\\\\=-15t^{2+7}u^{3+8}=-15t^9u^{11}$

$11.\\n-the\ number\\\\n^2=n+6\qquad\text{subtract}\ n\ \text{and}\ 6\ \text{from both sides}\\\\n^2-n-6=0\\\\n^2+2n-3n-6=0\\\\n(n+2)-3(n+2)=0\\\\(n+2)(n-3)=0\iff n+2=0\ \vee\ n-3=0\\\\n+2=0\qquad\text{subtract 2 from both sides}\\n=-2\\\\n-3=0\qquad\text{add 3 to both sides}\\n=3$

If it takes 6.9 pounds of seed to plant one acre of grass , how many acres can be planted with 8.28 pounds of seeds

Vaselesa [24]

There's 1.2 times as much seed, so you can plant 1.2 times more land.

1.2x1=1.2

So you can only plant 1.2 acres.

Taylor plans to use $2100 to open a savings account with an annual interest rate of 1.85%. How much more interest will he earn o

Ymorist [56]

Taylor will earn $21 more in compounded interest than in simple interest.

Given:
Principal = 2100
interest rate = 1.85%
term = 8 years

Simple Interest = Principal * interest rate * term
= 2100 * 1.85% * 8
= 310.80

Compounded Interest = Principal * (1+r)^t
= 2100 * 1.0185⁸
= 2100 * 1.158
= 2431.80

Interest from Compounded Interest : 2431.80 - 2100 = 331.80

Simple Interest = 310.80
Compounded Interest = 331.80

331.80 - 310.80 = 21
