A. After the mod. One wall is “x” longer than original (horizontal in diagram) and the other is “x” shorter (vertical)
(30+x)(30-x)
b. He original area = 30 x 30 = 900 sq. ft.
The mod. Area is (30+6)(30-6) = 36x24= 764 sq. ft.
So the room was largest to begin with when it was a square
Answer:
X=67
Step-by-step explanation:
x-22+135=180 (180 because that line is a straight line that was intersected and a straight line has a degree of 180)
x-22+135=180
x+113=180 (combine like terms)
x=67 (combine like terms again)
Check the picture below.
so it hits the ground when y = 0, thus
since "t" is seconds it took, it can't be a negative amount.
ANSWER: square root of 10
Rule: Pythagorean Theorem (a^2 + b^2 = c^2; side^2 + second side^2 = hypotenuse^2)
(substitute the missing side w/ a variable)
x^2 + 7^2 = (sqrt. 59)^2
x^2 + 49 = 59
x^2 = 10
x = sqrt. 10
The answer going to be -4
