i need with at least these questions.

1) multiply and simplify.

(3 + i)(4 + 2i) a) 7 + 3i b) 7 − 10i c) 10 + 10i d) 10 − 10i

2) what is the remainder r when the polynomial p(x) is divided by (x + 5)? is (x + 5) a factor of p(x)? p(x) = x3 - 5x2 + 2x - 10 a) -16i b) -16 c) -4i d) 4i

3) use the imaginary number "i" to rewrite the expression: the negative square root of -16 a) -16i b) -16 c) -4i d) 4i

4) use the imaginary number "i" to rewrite the expression as a complex number: square root with 100 + square root with -81 a) 9 i b) 10 + 9i c) 10 - 9i d) 19i

5) convert the expression cube root of 2 to exponential form. a) 21/3 b) 23 c) 32 d) 31/2

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.

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
