Factor the expression using the GCF. The expression 21m−49n factored using the GCF is...
Roman55 [17]

Answer:  7(3m - 7n)

<u>Step-by-step explanation:</u>

Factor each term then see what value(s) they have in common:

          21m         -          49n

            ∧                        ∧

          3 · 7 · m              7 · 7 · n

Both terms have a 7 in common.  What is left over after removing the 7?

21m: 7(3m)

49n: 7(7n)

GCF: 7           Leftovers: 3m <em>and</em>  7n

Factored form of expression is: 7(3m - 7n)

In ΔDEF, the measure of ∠F=90°, the measure of ∠E=32°, and FD = 9.6 feet. Find the length of EF to the nearest tenth of a foot.
NeX [460]

Answer:

EF=15.4\ ft

Step-by-step explanation:

we know that

In the right triangle DEF

tan(E)=\frac{FD}{EF} ----> by TOA (opposite side divided by adjacent side)

substitute the given values

tan(32^o)=\frac{9.6}{EF}

solve for EF

EF=\frac{9.6}{tan(32^o)}=15.4\ ft
