Candace paid her parents $45 for rent and divided the rest of her paycheck evenly into a checking account, savings account, and

Reika [66]

Answer:

p = $45 + 3($192)

Candace was paid $621.

Step-by-step explanation:

Let p represents the<u> paycheck</u>

Candace paid her parents $45 for rent

After paying the rent she evenly divided the rest of the amount into three parts.

She puts $ 192 into her savings account. It means that she also puts $192 into checking account and $ 192 into retirement fund

If we put the parts together, the equation we get is:

p = $45+$192+$192+$192

The equation can be summarized as:

p = $45 + 3($192)

We can read it as:

paycheck is equal to $45 plus 3 equal parts of $192 each

Now we can easily find how much was Candace paid.

p = $45 + 3($192)

p = $45 +$576

p = $621

Candace was paid $621.

What is the area of triangle ABC? Round to the nearest hundredth of a square unit. 17. 75 square units 81. 33 square units 372.

The area of the triangle ABC is 81. 33 square units.

We have to determine

What is the area of triangle ABC?

<h3>What is the formula for the area of a triangle?</h3>

The area of the triangle is determined by;

$\rm Area \ of \ triangle = s\sqrt{s(s-a)(s-b)(s-c)}$

Where the value of s is = a + b + c= 12 + 14 + 16 = 42

Substitute all the values in the formula;

$\rm Area \ of \ triangle = \sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area \ of \ triangle = \sqrt{21(21-12)(21-14)(21-16)}\\\\\rm Area \ of \ triangle = \sqrt{(21 \times 9 \times 7 \times 5)}\\\\Area \ of \ triangle =\sqrt{6,615}\\\\Area \ of \ triangle = 81.33$

Hence, the area of the triangle ABC is 81. 33 square units.

amid [387]

Answer:

(x+9)(3x+27)

Step-by-step explanation:

3x^2+54x+243 (243×3=729, Product=729, Sum=54) [27+27=54, 27×27=729]

3x^2+27x+27x+243

3x(x+9)+27(x+9)

=(x+9)(3x+27)

Converting the equation $x^2-20x+13=0$ into completing the square method we get: $\mathbf{(x-10)^2=87}$

Step-by-step explanation:

we are given quadratic equation: $x^2-20x+13=0$

And we need to convert it into completing the square method.

Completing the square method is of form: $a^2-2ab+b^2=(a-b)^2$

Looking at the given equation $x^2-20x+13=0$

We have a = x

then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20

So, 20x in form of 2ab can be written as: 2(x)(10)

So, we need to add and subtract (10)^2 on both sides

$x^2-20x+13=0\\x^2-2(x)(10)+(10)^2-(10)^2+13=0\\(x^2-2(x)(10)+(10)^2) \:can\: be\: written\: as\: (x-10)^2 \\(x-10)^2-100+13=0\\(x-10)^2-87=0\\(x-10)^2=87$

So, converting the equation $x^2-20x+13=0$ into completing the square method we get: $\mathbf{(x-10)^2=87}$
