write an expression to represent the area of a pool whose length is 5x + 1 unit and the width is 10 units

1 answer:

5 0

Area=length x width. Thus you would do 10 x (5x+1). You have to multiply both 5x and 1 by 10 to correctly distribute. So the final equation would be area=50x+10.

In 2007 Candace made 37 more field goals than she did in 2006, she had a total of 497 field goals for those years. How many fiel

d1i1m1o1n [39]

Heres what we know

X=2006 goals
y= 2007 goals
497 = X +Y which can be arranged to be y= 497 - x
y= 37 + x

soooo..
we make the y equations equal to each other

37 + x = 497 - x
2x = 460
x= 230

now plug that back into the original equation to check
y = 37 + (230)
y = 267

so in 2006 (remember x represents 2006 goals) she made 230 goals

12 bro it even says to follow the order of operations. If there is only addition and subtraction you just go from left to right. Same with if there is only multiplication and division.

Find the value of f(5) for the function. f(a) = 4(a + 4) - 3

MrRissso [65]

Answer:

$f(a) = 4(a + 4) - 3 = 4a + 16 - 3 \\ f(x) = 4a + 13 \\ f(5) = 4(5) + 13 = 20 + 13 \\ \boxed{f(5) = 33}$

<h2>33 is the right answer.</h2>
