b b b

a. 2log 7
b

b. log 10
b

c. log 4 + log 7
b b

d. log 6 - log 9
b b

please show the procedure thanks.

Options A,C and D are not equivalent

Step-by-step explanation:

1/2log49 + log 20 - log 14

=log 49½ + log 20 - log 14

=1og 7 + log 20 - log 14

=log (7 × 20 / 14)

=log 10

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
