Simplify the following expression.
(5h – 3)(5h – 3)

-30h +9

Step-by-step explanation:

25h²-30h+9

Step-by-step explanation:

we need to multiply binomials

to multiply binomials using the FOIL method, we first multiply the First terms (F for first) together (in this case, 5h and 5h)

That gives us 25h²

Next up, we do the Outer terms (O for outer), which in this case are 5h and -3. This gives us -15h

then, we do the two Inner terms, (I for inner)  which are -3 and 5h. This gives us -15h

finally, we do the two Last terms (L for last), which are -3 and -3. This gives us 9

here's what we have  from doing FOIL:

25h²-15h-15h+9

we can combine the 2 -15h's together to get:

25h²-30h+9

Hope this helps!

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

i pretty sure it is
