The expression for the area of frame is 4x² + 24x + 35
<h3>What is Area of rectangle?</h3>
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.
Here, Old length of photograph = 5 inch
Old width of photograph = 7 inch
Now, length of new photograph = (5 + 2x) inch
width of new photograph = (7 + 2x) inch
Now, Area of frame with new dimension = Length X breadth
= (5+2x) X (7+2x)
= 5(7+2x) + 2x(7+2x)
= 35 + 10x + 14x + 4x²
= 4x² + 24x + 35
Thus, the expression for the area of frame is 4x² + 24x + 35.

Answer:
9.1 = a+4
Step-by-step explanation:
The right side has two different values, variable <em>a,</em> constant 4.
The left side has the constant 9.1.
If both sides are equal, then
a + 4 should equal 9.1
Answer:
14, 15,16
Step-by-step explanation:
lets take "x" as the first integer
so since all the numbers are consecutive we can take integer number one as:
x
integer #2: x+1
integer#3:x+2
so
x+x+1+x+2=45
3x+3=45
3x=42
x=14
Hope this helps!
-5x+y=-3. (1) isolate y 1.First isolate a variable.( I isolated y because it was already isolated)
3x-8y=24. (2). 2.Then substitute that into the other equation
—————. 3. Then solve for X
Sub y=5x-3 into (2). 4. Then substitute X into one of the equations
5. Then solve for Y and ta-da you find the answer.
3x-8(5x-3)=24.
3x-40x+24=24. Hope this helped! :)
3x-40x=24-24
-37x=0
X=0
——————
Sub x=0 into (1)
-5(0)+y=-3
Y=-3
.: (0,-3)
