Answer:
612 cm²
Step-by-step explanation:
Total surface area = area of all the nets in that make up the shape
✔️There are 2 equal rectangles of the following dimensions:
L = 10 cm
W = 4 cm
Area = 2(10*4) = 80 cm²
✔️There are 2 equal rectangles of the following dimensions:
L = 10 cm
W = 17 cm
Area = 2(10*17) = 340 cm²
✔️There are 2 equal rectangles of the following dimensions:
L = 4 cm
W = 17 cm
Area = 2(17*4) = 136 cm²
✅Total surface area = 80 + 340 + 136 = 612 cm²
Answer:
Step-by-step explanation:
Hello,
Touchdown is 7 points, field goals is 3 points
Let's note a the number of touchdowns and b the number of field goals, we can write
(1) a + b = 80
(2) 7a + 3b = 516
(2) - 3*(1) gives
7a + 3b - 3(a + b) = 516 - 3*80
<=> 7a + 3b -3a - 3b = 516 - 240 = 276
<=> 4a = 276
<=>
And then from (1) b = 80 - 69 = 11
Hope this helps
Answer:
Step-by-step explanation:
First, you would have to make it so that T is on one side and everything else is on the other. You would end up with this:
T=1.04+5.60
Solve. You should get to this:
T=6.64
Answer:
71
-133
Step-by-step explanation:
Given the polynomial :
3x³– 4x² + 7x + 5, when x = 3 and also when
x = –3.
Put x = 3
3(3)³– 4(3)² + 7(3) + 5
3(27) - 4(9) + 21 + 5
81 - 36 + 21 + 5
= 71
Put x = - 3
3(-3)³– 4(-3)² + 7(-3) + 5
3(-27) - 4(9) - 21 + 5
-81 - 36 - 21 + 5
= - 133
