To find the x int, we will sub in 0 for y and solve for x...um...r
- 2r + 1/2y = 18
-2r + 1/2(0) = 18
-2r = 18
r = -18/2
r = -9
so the x int is (-9,0)
Answer: Many utility companies promote energy conservation by offering discount rates to ... who keep their energy usage below certain established subsidy standards. A recent EPA report notes that 70% of the island residents of Puerto Rico have reduced their electricity usage sufficiently to qualify for discounted rates.
Step-by-step explanation:
<h2>Given :-</h2>
- Area of Rhombus = Area of Triangle
- Base and Height of Triangle is 24.8 cm and 5.5 cm respectively .
- Length of one diagonal of the rhombus is 22 cm .
<h2>To Find :-</h2>
<h2>Solution :-</h2>
As we know that
Area of triangle = ½ × Base × Height
- Area = ½ × 24.8 × 5.5
- Area = 1 × 12.4 × 5.5
- Area = 12.4 × 5.5
- Area = 68.2 cm²
<h3 /><h3>Now,</h3><h3 />
Area of rhombus = ½ × D1 × D2
- 68.2 = ½ × 22 × D2
- 68.2 × 2 = 22 × D2
- 136.4 = 22 × D2
- 136.4/22 = D2
- 6.2 = D2
- D2=6.2
<h2>Hence :-</h2>
<h3>Other Diagonal is 6.2 cm.</h3>
Answer:
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = 0<em> x² + 6 x + 20</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the length of the rectangle = 2x +3
Given that the width of the rectangle = x +7
Perimeter of the rectangle = 2(length + width)
<u>Step(ii):-</u>
Perimeter of the rectangle = 2(length + width)
= 2(2 x +3 + x+7)
= 4x +6+2x+14
= 6 x +20
<u><em>Final answer:-</em></u>
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = o x² + 6 x + 20
