Answer:

√7 units, √98 units

Step-by-step explanation:

Pythagorean theorem

a^2+b^2=c^2. So 9+b^2=16. So b^2=7. So b=√7

a^2+b^2=c^2. SO 49+49=c^2. So 98=c^2. So c=√98.

Jin needs to fence in his rectangular backyard. The fence will have one long section away from, but parallel to, the length of h

Nookie1986 [14]

Answer: C. 9x+6 yd

Step-by-step explanation:

Given: The length of Jin's house= $3x+4\ yd$

The area of Jin's backyard= $9x^2+15x+4\ yd^2$

By middle splitting method, The area of Jin's backyard= $9x^2+12x+3x+4\ yd^2=(3x+1)(3x+4)\ yds$

To find the width of the backyard, divide the area by the length, we get

Width $=\frac{(3x+1)(3x+4)}{(3x+4)}=3x+1$

According to the question, only three sides need to fence

$Fencing=3x+1+3x+1+3x+4=9x+6\ yd$
