9. Divide -6 by 2 and then square it. -3^2=9
Answer:
Dante can make two different quadrilaterals with four sides equal
Step-by-step explanation:
we know that
A <u><em>rhombus</em></u> is a four-sided shape where all sides have equal length.
Also opposite sides are parallel and opposite angles are equal
A <u><em>square</em></u> has equal sides and every angle is a right angle (90°)
Also opposite sides are parallel.
therefore
Dante can make two different quadrilaterals with four sides equal
A Square and a Rhombus
Answer:
a = 12cm
Third option
Step-by-step explanation:
Use the pythagorean theorem because this is a right triangle and you are looking for a missing side.
The formula is:
a² + b² = c², where "a" and "b" are sides, but "c" is the hypotenuse (longest side).
We know the hypotenuse and one other side.
Substitute side "b" and "c".
a² + 5² = 13²
a² + 25 = 169 Isolate "a"
a² = 169 - 25 Subtract 25 from both sides
a² = 144 Find the square root of both sides
a = √144
a = 12
The mssing side, "a", is 12 cm long.
Answer:
5 bags
Step-by-step explanation:
Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags
The above provides 10pounds of potting soil already
Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil
We know that 1 bag contains 5/8 pounds of potting soil
x bags contain 3 pounds of potting soil
On cross multiplication we get
x = 
since x is an integer x = 5 bags
Note that an extra amount of soil will be remained unused
