Step-by-step explanation:
a = -2
b = 3
c = 5
<h2>Question:</h2>
= Solution,
= 3 ( - 2 ) × 5 - ( - 2 ) + 2 × 3
here ... ( + ) × ( - ) = ( - )
= - 6 × 5 - ( - 2 ) + 2 × 3
here .... ( - ) × ( - ) = ( + )
= - 6 × 5 + 2 + 2 × 3
= - 30 + 2 + 6
= - 30 + 8
here the ( - ) have greater variable so...
= - 22
hence - 22 is the answer . ....
Answer:
Area: 24 Perimeter: 20
Step-by-step explanation:
Area (multiply side 1 by side 2):
4×6=24
Perimeter (add all of the sides together):
4+4=8
6+6=12
8+12=20
1/tan(42)*18=20

1) 1000 / 100 ⇒ 10 / 1 = 10
1000 ÷ 100 = 10
100 ÷ 100 = 1
2) 9/81 ⇒ 1/9
9 ÷ 9 = 1
81 ÷ 9 = 9
3) 4/64 ⇒ 1/16
4 ÷ 4 = 1
64 ÷ 4 = 16
Answer:
6.28km
Step-by-step explanation:
Hey,
We know that the circumfrence is the perimetert of a full circle. If we want to find the perimeter of a semicircle all we have to do is find the circumfrence and then divide it by 2 since we want to know the perimeter of half the circle.
Circumfrence is equal to 2πr. Where r is the radius and since we know the radius we an solve for the circumfrence.
2(π)(1km)=2kmπ.
The problem tells us to use 3.14 for pi so let's multiply 2 by 3.14.
6.28km is the answer!
