Answer:
Axis of Symmetry = -4
Vertex = (-4,7)
Step-by-step explanation:
<span>2 consecutive numbers would be n + (n+1)
so you have n + n+1 = -49
combine like terms 2n +1 = -49
subtract 1 from each side:
2n = -50
divide both sides by 2
n = -25
n = -25
then the second number would be -25 +1, which = -24
so the answer is:
C. n + n + 1 = -49; n = -25; n + 1 = -24</span>
Answer:
the new frame is bigger than the original frame by 10%
Step-by-step explanation:
Let the length of the original frame be l,
then it's width is (10% of l)=×l
=
hence area of original frame=A=length×width
=
now the length of frame is enlarged by 10%
new lenght of frame=l+10%×l
=l+×l
=×l
width of new frame==
area of new frame=length×width
=
percent change=((area of new frame-area of old frame)×100)÷area of old frame
=10%
