Answer:

Step-by-step explanation:

If you are asking how old Sara is then....

the equation would be: S= (13×2)-3

(S is stands for Sara)

We are using 13 because Owen is 13 yrs old. We used 2 because it said twice. We are using three cause it said three less than. 13×2=26. 26-3 would be 23.

Place the following steps in order to complete the square and solve the quadratic equation,x^2+7=0

forsale [732]

X^2+7=0
this can be written as:
x^2+0x+7=0
To solve using completer square we proceed as follows:
x^2+0x=-7
but
c=(b/2a)^2
c=(0/2*1)^2=0
hence
x^2+0x+0=-7+0
this will be simplified as:
x^2=-7
getting the square root of both sides gives us:
sqrt(x^2)=sqrt(-7)
x=+/-√-7
but √-1=i
hence our answer will be:
x=+/-7i

Solve for x. write both solutions separated by a comma. 2x^2-5x+2=0

Nataly [62]

BY USING MIDDLE TERM SPLITTING,

2x^2-(4x+x)+2=0

(2x^2-4x)-(x-2)=0

2x(x-2)-1(x-2)=0

(2x-1)(x-2)=0

Two solutions are 2, 1/2

An algebraic expression is one that consists of both number(s) and an alphabet(s). The required answers are:

i. Distance from Chenoa's house to the coffee shop = 6.0 miles

ii. Distance from coffee shop to Chenoa's school = 1.5 miles

iii. Distance from Chenoa's house to her school = 7.5 miles

An algebraic expression is one that consists of both number(s) and an alphabet(s). The alphabet is referred to as the unknown whose value has to be determined.

In the given question, let the distance from the coffee shop to Chenoa's school be represented by y.

So that;

The distance from Chenoa's house to the coffee shop = (2y + 3) miles.

The total distance from Chenoa's house to her school = 5y.

This implies that:

(2y + 3) + y = 5y

3y + 3 = 5y

3 = 5y - 3y

2y = 3

y = $\frac{3}{2}$

= 1.5

The distance from the coffee shop to Chenoa's school is 1.5 miles.

Thus;

(2y + 3) = ( 2(1.5) + 3)

= 6

The distance from Chenoa's house to the coffee shop is 6 miles.

And,

5y = 5(1.5)

= 7.5

The total distance from Chenoa's house to her school is 7.5 miles.
