1. (k+7)² =289 2. (2s-1)² =225 3. (x-4)² =169 please help me answer these :)

professor190 [17]

$(k+7)^2 =289\\
|k+7|=17\\
k+7=17\vee k+7=-17\\
k=10 \vee k=-24$

$(2s-1)^2 =225\\
|2s-1|=15\\
2s-1=15\vee 2s-1=-15\\
2s=16 \vee 2s=-14\\
s=8 \vee s=-7$

$(x-4)^2 =169\\
|x-4|=13\\
x-4=13 \vee x-4=-13\\
x=17 \vee x=-9$

Why does a square with an area 20² not have a whole number side length.

Klio2033 [76]

Answer:

This is because the number '20' is not a perfect square.

Step-by-step explanation:

If you find $\sqrt{20}$ , you will be getting 4.4721935955... which is not a whole number, thus 20 is not a perfect square.
