Answer:

(b) is correct.

Step-by-step explanation:

We substitute the given value of x in each equation and see if they fit.

a) 3x + 7 = 10 Plug in x = -1:

3(-1) + 7 = 4 so this solution is incorrect>

b) is correct because

5(5+4) - 5 = 45 - 5 = 40.

Answer:

150 feet of flowers would be planted along side C

$a=5400$

Step-by-step explanation:

Use the pythagorean theorem to find the length of side C

$a^2+b^2=c^2$

Input the corresponding numbers into the formula

$90^2+120^2=c^2$

$c^2=22500$

$c = \sqrt{22500} \\ c=150$

150 feet of flowers would be planted along side C

To find the area multiply the base and height together, and divide the total by two

$a = \frac{bh}{2}$

$a = \frac{90 * 120}{2} \\ a=5400$
