The answer is (A) 5.5 centimeters. The height is found by 33/6, since the area of a parallelogram is base*height.
The second one and the last one
Answer:
x= √10 and x= -√10
Step-by-step explanation:
first look to isolate the term with the variable on one side
-5 +5 -2x² = -5 -15; subtract 5 from both sides(inverse of addition)
-2x² = -20; divide both sides by -2 (inverse of multiplication)
x² = 10; square root both sides (the inverse of raising to power of 2)
√x² =√10
x =±√10
Answer:
1 feet wide
Step-by-step explanation:
We first need to find the area of the floor.
6*5=30
Then we divide the area by the number of kitchen tiles to get the area of each tile.
30/10=3
After this, we set up a L x W = A equation to solve for w.
3*w=3
3w=3
w=1
F(x)=x^2+6x+3
seperate x terms
f(x)=(x^2+6x)+3
take 1/2 of 6 and square it
6/2=3
3^2=9
add negative and positive inside parenthasees
f(x)=(x^2+6x+9-9)+3
factor perfect square
f(x)=((x+3)^2-9)+3
get rid of parenthasees
f(x)=(x+3)^2-9+3
f(x)=(x+3)^2-6
last one is answer
