31 rounds to 30

307 rounds to 310

30+m≈310

m≈310-30

m≈280

M = 276

307-31 = 276 so, 31+276=307

Answer:

a^5x^5, 10a^5x^4, 40a^5x^3

Step-by-step explanation:

Use pascal's triangle for the first one

(2+x)^5 * a^5

= x^5a^5 + 5*2^1*x^4*a^5 + 10*2^2*x^3*a^5 ...

= a^5x^5 + 10a^5x^4+ 40a^5x^3 ...

Answer:

$a=22.5\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

In this problem

If polygon RSUPE is similar to polygon KQUIC

then

$\frac{RS}{KQ}=\frac{RE}{KC}$

substitutes the values and solve for a

$\frac{a+2}{14}=\frac{17.5}{10}\\ \\10a+20=14*17.5\\ \\10a=245-20\\ \\a=225/10\\ \\a=22.5\ units$

Lines L and M are parallel. Lines t^1 and t^2 are transversals. What is m<1 if m<4=65*? Justify your answer. (Ps- there is

Diano4ka-milaya [45]

The complete question in the attached figure

we know that
m∡4=65°
m∡4=m∡2---------> by internal alternate angles
m∡5=m∡3---------> by internal alternate angles

m∡1=180°-m∡2---------> 180°-65°--------> m∡1=115°

the answer is
m∡1=115°
