4(-3)^2-5(-13)
-7^2+15
-7^17
<em>Answer:</em>
<em> $ 34, 34</em>
<em>Step-by-step explanation:</em>
<em>1800 mm = 1, 8 m</em>
<em>1200 mm = 1, 2 m</em>
<em>A = 1,2 × 1,8 = 2, 16 m²</em>
<em />
<em>1 m² ..................... $ 15.90</em>
<em>2, 16 m² .............. $ x</em>
<em>x = 2,16×15,90/1 ≈ $ 34, 34</em>
