Answer:
Step-by-step explanation:
(x+1 = whatever the letter x represents the multiply it to 4 then do 2. - 3= -1 x 5= 4 + the sum of 1 and x times 4. Hope it helps <3
You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So:
x^2+x^2=8
2x^2=8
2/2x^2=8/2
x^2=4
√x^2=√4
x=2
The side of the square is 2.
So now the area of a square is:
Side×Side
2×2=4
The area of the square is 4 centimetres
The answer is B. 1/3
√5/√45 <— simply both terms by 5
= √1/√9 <— √5÷5 = 1 and √45 ÷ 5 = √9
= 1/√9
= 1/3
√1 = 1
(you can write 1 directly instead of √1)
√9 = 3
