Answer:
x = 44
Step-by-step explanation:
sqrt(x+5) -3 =4
Add 3 to each side
sqrt(x+5) -3+3 =4+3
sqrt(x+5) =7
Square each side
(sqrt(x+5))^2 =7^2
x+5 = 49
Subtract 5 from each side
x+5-5 = 49-5
x=44
Answer:
Step-by-step explanation:
<u>Sides of the picture added margin:</u>
<u>Solution</u>:
- A(margin) = Total area - A(picture)
- (8 + 2x)(5 + 2x) - 5*8 = 30
- 4x² + 10x + 16x + 40 - 40 - 30 = 0
- 4x² + 26x - 30 = 0
- 2x² + 13x - 15 = 0
- x = (-13 + √(13² + 2*4*15))/4
- x = (-13 + 17)/4
- x = 1 cm
Note. The other root is ignored as negative.
The correct answer to this is “True”.
Symmetry signifies balance and form. An object with
rotational symmetry will still look the same after a rotation. Since it maintains
its shape and figure after being rotated, therefore its characteristics such as
length of the diagonals, the angles of each corner, or parallelism of opposite
sides will remain the same.
Answer:
Screen 1: 200, Screen 2: 125 , Screen 3: 175
Step-by-step explanation:
Screen 1
Multiply 40% and 500
Convert 40% to a decimal
40/100=0.40
500*0.40
200
Screen 2
Multiply 25% and 500
Convert 25% to a decimal
25/100=0.25
500*0.25
125
Screen 3
Subtract the amount of people that went to screens 1 and 2 from the total
500-200-125
175
So, Screen 1 had 200 visitors, 2 had 125 and 3 had 175
Hope this helps! :)
Answer:
Option C.
Step-by-step explanation:
Given: In 
.
In 
,
(Angle sum property)
Now,
In a triangle, the greatest angle has largest opposite side and smallest angle has smallest opposite side. So, we conclude that
Therefore, the correct option is C.
