Step-by-step explanation:
the lengths OB, OC & BC together forms a isosceles triangle.
therefore,
OB=OC
3x+4=x+8
2x=4
x=2.
OB = 3x+4= 3.2+4=10cm.
OC= x+8= 2+8=10cm.
therefore, the diagonals are : 20cm each.
hope this helps you.
Answer: 46-3i
Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.
(6+7i)(3−4i)
18−24i+21i+28
(18+28)+(−24i+21i)
46-3i

1) circumference= 3.14 x 12
C= 37.68
The answer is: [D]: " 24 + 2w " .
___________________________________________
Explanation:
___________________________________________
Given: The formula for the Perimeter of a rectangle:
___________________________________________
P = 2L + 2w ;
in which:
P = perimeter ;
L = length = 12 units (given);
w = width = unknown;
_______________________________________________________
Find the perimeter, "P", in terms of "w" ; since "w" (width) is unknown; and considering the answer choices given; along with the information provided in the problem, we only have enough information to solve for the perimeter, "P", in terms of "w" ;
_____________________________________________________
So, given the formula/equation for the perimeter, "P" :
_____________________________________________________
P = 2L + 2w ; we know that: " L = 12 units " ;
_____________________________________________________
P = 2*12 + 2w = 24 + 2w ; which is: "Answer choice: [D]" .

To solve, you need to carry the decimal two spaces to the right because there are two zero in 100 so 0.17 times 100 is 17. The height of the tree after ten years was 17 meters tall in height.
