Answer: $\text{Area of the square shaped traffic sign }=16x^2+9+24x$

Step-by-step explanation:

Given: The side of the square shaped traffic sign = 4x+3

We know that the area of square is given by:-

$Area= side^2$

Therefore, the area of the side of the square shaped field is given by:-

$Area=(4x+3)^2$

We know that , $(a+b)^2=a^2+b^2+2ab$

Therefore,

$(4x+3)^2=(4x)^2+(3)^2+2(4x)(3)\\=16x^2+9+24x$

Hence, $\text{Area of the square shaped traffic sign }=16x^2+9+24x$

If y varies directly as x, and y=6 as x=-1, find y for the x-value of 5

Tema [17]

Answer:

$y=-30$

Step-by-step explanation:

we are given

y varies directly as x

so, we can write equation as

$y=kx$

where

k is constant of proportionality

We have

at x=-1 , y=6

so, we can use it to find k

$6=k(-1)$

so, we get

$k=-6$

now, we can plug it back

$y=-6x$

now, we can plug x=5

and we get

$y=-6\times 5$

$y=-30$

For each container of tea, McKenzie uses 16 tea bags and 3 cups of sugar. If McKenzie uses 64 tea bags, how many cups of sugar w

cestrela7 [59]

So tis is a ratio 16 is to 3 or 16:3
if use 64 tea bags then how many cups of sugar so
turn 16:3 into fraction
16:3=16/3 or 3/16, it doesn't matter
then you want to find 64:x or 64/x or x/64

we know that 16/3=64/x because it tis an equivalent ratio
so 16/3=64/x
multiply both sdies by (3 times x)
16 times x times 3/3=64 times 3 times x/x
16 times x=64 times 3
16x=192
divide both sdies by 16
x=12
theanswer is 12 cups of sugar

How would I simplify 53-2(16/8*16-7)

Oduvanchick [21]

The simplified form of the expression is 3

<h3>Simplifying an Expression</h3>

From the question, we are to simplify the given expression

The given expression is

53 -2(16/8 * 16-7)

Simplifying

Using BODMAS

53 -2(16/8 × 16-7)

53 -2(2 × 16-7)

53 -2(32-7)

53 -2(25)

53 -50

= 3

Hence, the simplified form of the expression is 3
