Answer: The correct equation is (d). 15 + 40 = 5(3 + 8).

Step-by-step explanation: We are given to select the correct equation from the options that demonstrates the distributive property.

DISTRIBUTIVE PROPERTY: For any three real numbers a, b and c, the distributive property can be written as

(i) a(b + c) = ab + ac,

(ii) (a + b)c = ac + bc.

Out of the given for equations, only equation (d) gives the distribution of 5 over the addition of 3 and 8.

We have, according to the distributive property,

5(3 + 8) = 5 × 3 + 5 × 8 = 15 + 40.

Thus, the correct option is (d).

Find the measure of the exterior angle. *

MatroZZZ [7]

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O \: N}}} }:$

Set up an equation and solve for x :

⋆ $\large{ \bf{(4x + 9) \degree = 2x \degree + (3x - 12) \degree}}$ [ Exterior angle is always equal to the sum of two non - adjacent interior angles ]

~Remove the unnecessary brackets

⟶ $\large{ \bf{4x \degree + 9 \degree = 2x \degree + 3x \degree - 12 \degree}}$

~Add the like terms : 2x ° & 3x°

⟶ $\large{ \bf{4x \degree + 9 \degree = 5x \degree - 12 \degree}}$

~Move 4x to right hand side and change it's sign

~Similarly move 12 to left hand side and change it's sign

⟶ $\large{ \bf{9 \degree + 12 \degree = 5x \degree - 4x \degree}}$

⟶ $\large{ \bf{21 \degree = x \degree}}$

⟶ ${ \large{ \bf{x = 21 \degree}}}$

Now , Substituting the value of x in (4x+9)° [ Exterior angle ]

⤿ $\large{ \bf{4 \times 21 \degree + 9 \degree}} = \boxed{93 \degree}$

☥ $\boxed{ \boxed{ \large{ \tt{Our \: Final \: Answer : \boxed{ \underline { \tt{93\degree}}}}}}}$

A cheetah ran 300 feet in 2.92 seconds . What was the cheetah's average speed in miles per hour ? Show your work .

vivado [14]

Cheetah ran 300 feet in 2.92 seconds.

Average speed in miles per hour.

Converting 300 feet to mile.
5280 feet = 1 mile
1 feet = (1/5280) mile
300 feet = (1/5280) * 300 = (300/5280) = (30/528) = (10/176) mile.

2.92 seconds to hour.
3600 seconds = 1 hour
1 second = (1/3600) hour
2.92 seconds = 2.92 * (1/3600) = (2.92/3600) hour.

Speed of Cheetah in miles per hour = (10/176) mile / (2.92/3600) hour
= 70.05 miles/hour

Which equation represents the graphed function?

makvit [3.9K]

The equation y = –2 x + 3 represents the graphed function.

Answer: Option A

Step-by-step explanation:

As per the mapping points in the attached figure, A (0, 3) and B (1, 1)

Step 1: Find the slope of the line.

We know that the formula to calculate the slope between two points is equal to

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
