If the diagonals of a quadrilateral are perpendicular, then it is a rhombus. False, diagonals don't have to be congruent or bisect each other. The diagonals of a rectangle bisect its angles. A kite with all consecutive angles congruent must be a square.
Answer:
9ab - 9a +1
Step-by-step explanation:
first, we can distribute the negative sign to the second set of parentheses.
-(-4ab + 5) becomes + 4ab - 5
now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5
5ab + 4ab - 9a - 4 - 5
= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.
Answer:
C. 364.4
E. 14
F. 21
G. 96°
The "distance formula" an extension of the Pythagorean Theorem is:
d^2=(x2-x1)^2+(y2-y1)^2 in this case:
d^2=(-8-7)^2+(-9--1)^2
d^2=(-15)^2+(-8)^2
d^2=15^2+8^2
d=√(15^2+8^2)
So the answer is 15^2+8^2
Answer:
54 inches
Step-by-step explanation:
At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake
Step 1
We would be converting the length of the Royal's pet snake to inches
1 foot = 12 inches
8 feet = x
Cross Multiply
x = 8 × 12 inches
x = 96 inches
Step 2
How many inches longer is Royal's snake?
This is calculated by subtracting the length of the Royal's pet snake from the least length
= 96 inches - 42 inches
= 54 inches
Therefore, the Royal's snake is 54 inches longer
