Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
4.5 and 3.5 it is the same but 4 and 3 are different you get it ?
Answer:
About 8.6
Step-by-step explanation:
d=(x2-x1)^2+(y2-y1)^2
8=x1 8=y1 3=x2 1=y2
(3-8)^2+(1-8)^2
(-5)^2+(-7)^2
25+49
74
take the square root and you get about 8.6
Quadratic Equation in Standard Form: ax2 + bx + c = 0.
Quadratic Equations can be factored.
Quadratic Formula: x = −b ± √(b2 − 4ac) 2a.
When the Discriminant (b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions.
HOPE THIS HELPS!!!
