Saying 25+ -8 is basically saying 25-8, and since 25 is the bigger number and it's positive, you get positive 17

Answer:

Step-by-step explanation:

Well if I’m correct it should equal 17 because anything plus a negative number is usually just subtracting. Sorry if this is a bad explanation it’s harder to put it into words.

A garden is made up of two squares and a quarter circle. What is the area of the garden?

Elanso [62]

9514 1404 393

Answer:

100.27 ft^2

Step-by-step explanation:

The area of each square is ...

A = s^2 = (6 ft)^2 = 36 ft^2

The area of the 1/4 circle is ...

A = 1/4πr^2 = 1/4π(6 ft)^2 = 9π ft^2 ≈ 28.27 ft^2

The area of the garden is the sum of the areas of the quarter circle and the two squares:

A = 28.27 ft^2 + 2×36 ft^2 = 100.27 ft^2

The area of the garden is about 100.27 square feet.

Lexi is making a scale drawing of a soccer field that is 120 yards long and 80 yards wide and the field is that see strong is 30

vekshin1

Answer:

45 cm

Step-by-step explanation:

l = Length of football field is 120 yards

w = Width of football field is 80 yards

The ratio of the sides is $\dfrac{l}{w}=\dfrac{120}{80}=\dfrac{3}{2}$

Now the width of the field is 30 cm = w'

$\dfrac{l'}{w'}=\dfrac{l}{w}\\\Rightarrow l'=\dfrac{l}{w}\times w'\\\Rightarrow l'=\dfrac{3}{2}\times 30\\\Rightarrow l'=45\ \text{cm}$

The length of the field in the drawing is 45 cm.

Is the answer true or false?

stira [4]

Answer:

The answer to your question is False

Step-by-step explanation:

Original division

$\frac{3x^{3}+ 5x^{2}- 11}{2x + 1}$

Process

1.- To express a division in a synthetic form we must take the coefficients of the numerator. If there is no coefficient for a variable, we write it as 0.

3x³ + 5x² - 11 = 3 5 0 - 11

The "0" means 0x, this term is not present but we must consider it.

2.- Solve the denominator for x

2x + 1 = 0

2x = -1

x = -1/2

3.- Write the synthetic division

-1/2 3 5 0 -11
