Evaluate the expression 3(7 + 4)2 − 14 ÷ 7. 50 361 363 586
Kipish [7]
It appears that none of your option choices are correct,, are you sure you copied them right ? I will show you how to solve this and how I got my answer.
The first step for solving this is to add the numbers in the parenthesis.
3 × 11 × 2 - 14 ÷ 7
Divide -14 by 7.
3 × 11 × 2 - 2
Divide the first 3 numbers together.
66 - 2
Subtract the numbers together to get your final answer.
64
Let me know if you have any further questions.

If f(a)=(a•a•a)-(a•a) + a-1 what is the value of f(-3)?
Elena L [17]

Answer:

-40

Step-by-step explanation:

f(a) = a³ - a² + a - 1

f(-3) = (-3)³ - (-3)² + (-3) - 1

f(-3) = (-27) - (9) + (-3) -1

f(-3) = -27 - 9 -3 - 1

f(-3) = -40

Circle G and X connect at point Y. The length of G Y is 10 centimeters and the length of Y X is 16 centimeters.
In-s [12.5K]

Answer:

676π Sq. cm.

Step-by-step explanation:

The line GY is the radius of the circle with G as center and Y is a point on the circle.

Now, GY = 10 cm.

Again, the line XY is the radius of the circle with X as center and Y is a point on the circle.

Now, XY = 16 cm

The two circles touched at point Y,

Therefore, point Y will be on line GX.

Now, GX = GY + YX = 10 + 16 = 26 cm.

Therefore, Marco wants to create a new circle using GX as the radius, then the area of the new circle will be π (26)² Sq. cm. = 676π Sq. cm. (Answer)
