The perimeter p of the rectangle with length l and width w is:
p = 2l + 2w
that is, two times its length and two times its width, lets solve for the width w and substitute known data:
<span>p = 2l + 2w
</span>2w = p - 2l
w = (<span>p - 2l</span>)/2
w = (56 - (2*12))/2
w = (56 - 24)/2
w = 32/2
w = 16
therefore the width of the rectangle is 16 in
1/4 .....divide the pizza by 4 ...so you get 1/4 ...taken by each friend !
If a figure is dilated it keeps the same shape so the angles of the triangle will be the same as before dilation
Therefore the tan of the angle will also be the same.
Answer:
A
Step-by-step explanation:
Answer:
(- 3, 0 ) and (1, 0 )
Step-by-step explanation:
Given
y =2x² + 4x - 6
To find the x- intercepts let y = 0, that is
2x² + 4x - 6 = 0 ← divide all terms by 2
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
The x- intercepts are (- 3, 0 ) and (1, 0 )
