The answer is two, please mark me as brainliest lol
here,
length(l) = x+7
breadth =. x+1
area of rectangle = l * b
i.e. ( x+7) ( x+1)
= x^2+8x+7
The answer is 42
the equation x2-11+42 means that 7 and 6 added equal 11 but multiplied equal 42

<u />
<u>Step 2: Solve for </u><em><u>y</u></em>
- Cross-multiply:
- Multiply:
- Isolate <em>y</em>:
- Rewrite:
<u>Step 3: Check</u>
<em>Plug in y to verify it's a solution.</em>
- Substitute:
- Divide:
Here, we see that 3.125 does indeed equal 3.125. ∴ y = 1.44 is a solution of the equation.
Applying log rules leaves us with the following equation:
x^2 + 8 = 6x
Change to standard form and solve using factoring.
x^2 - 6x + 8 = 0
(x - 4)(x - 2) = 0
x = 4
x = 2
Hope this helps!
