Answer:
Width=13cm
Length=18cm
Step-by-step explanation:
Width of the Initial Photograph=9cm
Length of the Initial Photograph=14cm
If width and length are increased by an equal amount, say x
New Width=9+x
New Length=14+x
Area of the new photo is 108 square centimeters greater than the area of the original photo.
Area of Original Photo=14*9=126cm²
Aeea of the New Photo=126+108=234cm²
Therefore:
(9+x)(14+x)=234
126+9x+14x+x²-234=0
x²+23x-108=0
x²+27x-4x-108=0
x(x+27)-4(x+27)=0
(x+27)(x-4)=0
x+27=0 or x-4=0
x=-27 or x=4
Since x≠-27
x=4cm
The dimensions of the new photo are:
Width=9+x=9+4=13cm
Length=14+x=14+4=18cm

Answer:
Step-by-step explanation:
What variable are you solving for?
-4x+y=29
y=29-(-4x)
y=29+4x
y=4x+29
----------------
-4x=29-y
-4x=-y+29
x=1/4y+29/-4
y=1/4y-29/4
Answer:
yes
Step-by-step explanation:
(5_3)^2+2(0)=4
substitute with the 5 to x and 0 to y
X+3≤ -5+2x
Add 5 to the other side. (the inverse of subtraction, since 5 is negative)
x+8≤2x
Subtract x on both sides.
8≤x <- the answer
I hope this helps!
