Hello mere if you wanna beon the brainy mark

Step-by-step explanation:

19) −534)(−72)

=38448 POSITIVE

20) −2435(Decimal: -48.6) NEGATIVE

21) −285−629

=−285−629

=−285+−629

=−914 NEGATIVE

22)−455+801

=−455+801

=346 POSITIVE

23)(62)(−1014)

=−62868 NEGATIVE

24) −298−(−298)

=−298−(−298)

=−298+298

=0 ZERO

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
