Answer:
£3.66
Step-by-step explanation: if you need it :D
17 + 23 = 40
40 = 16 what about 17
16 × 17 = 272 ÷ 40 = £6.8
16 - 6.8 = £9.2
20% of £6.8 = £1.36
1/4 of £9.2 = £2.3
1.36 + 2.3 = £3.66
Can you mark my answer brainliest? Tysm! :D

Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>142</u></em><em><u>°</u></em></h2>
Step-by-step explanation:
This is because,
They are <em><u>Vertically</u></em><em><u> </u></em><em><u>Opposite</u></em><em><u> </u></em><em><u>Angles</u></em><em><u>. </u></em>
Area of Square = Base*Height
Base=(x+1) Height=(x+1)
Therefore Area=(x+1)(x+1) or (x+1)^2
By expanding the brackets e.g. x*x is x^2 then x*1 is x and so on you get:
x^2+x+x+1 this simplfies to x^2+2x+1
Area = x^2=2x+1
Unless they have given you a value for x, this is the equation for the area of said square.
can u plz take a more clearer photo of the problem and also try to elaborate
