Do all squares have two pairs of parallel sides?Explan

Yes any square is also a parallelogram, but not the other way around (some parallelograms are not squares). In other words, any square is a parallelogram.

If you draw a Venn Diagram, the set of squares will be entirely inside the set of parallelograms.

This is because any rhombus is also a parallelogram, and the same applies to rectangles as well. A square is the combination of a rhombus and rectangle.

Rhombus = four sided figure where all sides are equal

Rectangle = four sided figure where all angles are equal to 90 degrees

Solve for z. -p(d+z) = -2z+59−p(d+z)=−2z+59

Answer:

$\bold{z=\dfrac{pd+59}{p+2}}$

Step-by-step explanation:

-p(d + z) = -2z + 59

-pd - pz = -2z + 59

+pd +pd

-pz = pd - 2z + 59

+2z +2z

pz + 2z = pd + 59

(p + 2)z = pd + 59

÷(p+2) ÷(p+2)

$\bold{z=\dfrac{pd+59}{p+2}}$

Given: F(x) = 3x ^2 + 1, G(x) = 2x - 3, H(x) = x H -1 (x) = x 1/x -x

just olya [345]

If I understand right you want the inverse of H(x)

H(x)=x
y=x
to calculate the inverse, isolate x, which is already the case, switch x and y, which doesn't change anything and that is your new function
the inverse is the same function in this case

so H⁻¹(x)=x

Okay so you are going to really just add 30 + 9 here and that means you have 30 tens and 9 ones or a 30 in the tens place and a 9 in the ones place.

I hope i broke that down well enough.

I hope this helped :)

Answer: 8/15

Step-by-step explanation:

Vertical: there are 4 shaded squares out of 5 total squares → 4/5

Horizontal: there are 2 shaded squares out of 3 total squares → 2/3

$\dfrac{4}{5}\times \dfrac{2}{3}\quad =\large\boxed{\dfrac{8}{15}}$
