<span><span>The sum of a squared and b is given by
$a^2+b$

</span>7 times the sum of a squared and b is given by
</span><span> $7(a^2+b)$
while 4 times the sum of a squared and b is given by
</span> $4(a^2+b)$

Therefore, <span>7 times the sum of a squared and b minus 4 times the sum of a squared and b is given by

$7(a^2+b)-4(a^2+b)=3(a^2+b)$ </span>

James decides to walk from school to the park to play ball. The park is only 0.5 mile from the school. He leaves school at 3:15

miskamm [114]

Answer: C

Step-by-step explanation: We see that it took James 10 minutes to go 0.5 miles, so to get how many miles an hour James is traveling, we need to get the miles to 1. To do this, multiply by 2, and this will give you that it took James 20 minutes to go 1 mile. This is option C.

Solve this equation for a: 6a+3=45

fenix001 [56]

Answer: 7

Step-by-step explanation:

Step 1: Subtract 3 from both sides.

6a+3−3=45−3

6a=42

Step 2: Divide both sides by 6.

6a /6 = 42 /6

if an exterior angle of a regular polygon measures 15 degrees how many sides does it have ?a.23. b.24. c.25

dimaraw [331]

Answer:

B.24

Step-by-step explanation:

we know,

exterior angle = 360°/n(where 'n' is number of sides)

then,

15° = 360°/n

n = 360°/15°

n = 24

Find the area between the graph of the function and the x-axis over the given interval, if possible.

vodomira [7]

Answer:

$A= -\frac{5}{-1} - \lim_{x\to\infty} \frac{5}{x-2} = 5-0 = 5$

So then the integral converges and the area below the curve and the x axis would be 5.

Step-by-step explanation:

In order to calculate the area between the function and the x axis we need to solve the following integral:

$A = \int_{-\infty}^1 \frac{5}{(x-2)^2}$

For this case we can use the following substitution $u = x-2$ and we have $dx = du$

$A = \int_{a}^b \frac{5}{u^2} du = 5\int_{a}^b u^{-2}du$

And if we solve the integral we got:

$A= -\frac{5}{u} \Big|_a^b$

And we can rewrite the expression again in terms of x and we got:

$A = -\frac{5}{x-2} \Big|_{-\infty}^1$

And we can solve this using the fundamental theorem of calculus like this:

$A= -\frac{5}{-1} - \lim_{x\to\infty} \frac{5}{x-2} = 5-0 = 5$

So then the integral converges and the area below the curve and the x axis would be 5.
