Answer:

6. (a-4)(a+9)

7. (3p+4)(p-2)

8. Will explain below.

9. (5b+4)(5b-4)

Step-by-step explanation:

HELLOOO IM BACK

6. -4*9 = -36 (the variable), 9-4 = 5 (a) , so a^2 +5a - 36 is fulfilled.

7. 4*-2 = -8, 4-2 = 2, so 3p^2 - 2p - 8 is fulfilled.

9. 25b^2 = (5b)^2

16 = 4^2

Using the difference of squares formula, a^2-b^2= (a+b)(a-b)

saveliy_v [14]

Answer:

8(1/x) = 4(1/10)

Step-by-step explanation:

lets say the number is x

eight times the reciprocal of a number equals 4 times the reciprocal of 10

8 * 1//x = 4 * 1/10

8/x = 4/10 , cross multiply

4x =8*10, divide both sides by 4

x= 80/4

x= 20

Anika buys a pair of shin guards for $8.58 and serveral pairs of soccer socks for $4.29 per pair. If she spends 25.74 before tax

Kryger [21]

Answer: 4 pairs of socks

Step-by-step explanation:

According to the described situation, Anika spends $\$25.74$ in 1 pair of shin guards for $$8.58$ and $x$ pairs of socks for $\$4.29$ each pair.

So, we can express this in the following equation:

$\$25.74=$8.58+\$4.29 x$

Isolating $x$ we will find the pairs of socks:

$\$25.74-$8.58=\$4.29 x$

$x=\frac{\$17.16}{\$4.29}$

$x=4$ Hence, Anika bought 4 pairs of socks.
