Answer:
Step-by-step explanation:
This formula does not seem to be among the answer choices.
W = (P/2) -L
8 goes to 6 that’s -2 then goes back to 8 then goes to 7 that’s -1 add -1 and -2 and you get -3 but you add it like before so it’s 7 to 10 so then it’s 10 -4 to 6 then goes back to 10 to where you add 4 to get 14
Answer:
A is TRUE (44 in²*2=88 in²)
B is FALSE x(x-3)=88 (the rectangle) or x(x-3)/2=44 (the triangle)
C is TRUE if x(x-3)=88==>x²-3x-88=0
D is TRUE :
x²-3x-88=0
Δ=9+4*88=361=19²
==>x= 11 or x=-8 (excluded for <0)
E is FALSE for 11*4≠88
Step-by-step explanation:
correct me if i am wrong
Given:
a square with an area of a² is enlarged to a square with an area of 25a².
The side length of the smaller square was changed when The side length was multiplied by 5.
Area = (1a)² = a²
Area = 1a * 5 = 5a ⇒ (5a)² = 25a²
