Answer:

119 cm^2.

Step-by-step explanation:

Perimeter = 2(L + W)       where L = length and W = the width.

L = W+10 (given).

So substituting the given values:

48 = 2(L + W)

48 = 2(W+10 + W)

2(2W + 10) = 48

2W + 10 = 48/2 = 24

2W = 24 - 10 = 14

W = 7 cm.

So L = 17 cm.

Area = 7 * 17

= 119 cm^2.

The equality used is Subtraction property of equality

Option A is correct

Step-by-step explanation:

We need to identify which option best explains or justifies Step 1.

Step 1 is: -c = ax^2 + bx

The given equation is: 0 = ax^2 + bx + c

To get the equation for step 1 we need to subtract c on both sides of equation i.e using subtraction property of equality

0-c = ax^2 + bx + c-c

-c = ax^2 + bx

So, The equality used is Subtraction property of equality

Option A is correct.

PLS HELP MEE ASAP 1 MIN LEFT HELPP!!!!!!!!!
artcher [175]

Answer: BC = 5.83

Step-by-step explanation:

Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:

AB = 5

AC = 3

BC = ?

To find BC, we can simply use the Pythagorean Theorem:

a^{2}+b^{2}=c^{2}

5^2 + 3^2 = c^2

25 + 9 = c^2

34 = c^2

Now square root to find c, or BC.

\sqrt{34}=\sqrt{c^{2} }

c = 5.83 (rounded by nearest hundredth)
