I is equal to negative 1
1) 5-2i or 5-2
2) 7-3i or 7-3
Answer:
-3 + 5 = 2
-3 + -2 = 1
-2 + -1 = -3
5 - -1 = 6
Step-by-step explanation:
Answer:

7 cabins takes 14.7 trees
Step-by-step explanation:
divided 10.5 by 5= 2.1 trees per cabin
2.1 x however many cabins your gonna build
First you need to form a worthy equation using slope-intercept (y=mx+b). Do that by counting the slope and finding the y-intercept. Then you have to choose between < or > to make it more accurate. In order to do so, you would have to pick a point with a point x and y and see wether or not I’m the equation is true when you put it in the blanks. If it’s true then you would shade whichever region the point is. If it’s false then shade the opposite region.
Good luck!!!!!!! :)
1. The shape of cross-section is a circle.
2. The face parallel to ABCD is EFGH. Since this is a a rectangular shape,
A = L*H = 12*6 = 72 cm^2
3. The cross-section parallel to ABC is DEF with h = 12 ft, b= 5ft (where h is the height and b is the base of a right angled triangle).
Area, A = 1/2 *b*h = 1/2*5*12 =30 ft^2
4. Plane BDHF is a rectangle shape whose length is the diagonal of ABCD.
Diagonal BD = sqrt (AB^2+BD^2) = sqrt (8^2+7^2) = 10.63 cm.
Perimeter, P = 2(BD+DH) = 2(10.63+6) = 33.26 cm
