Answer:

x = -3; y = -3

Step-by-step explanation:

x = 2y + 3

y = 2x + 3

x = 2(2x + 3) + 3

x = 4x + 6 + 3

-3x = 9

x = -3

y = 2x + 3

y = 2(-3) + 3

y = -3

Answer: x = -3; y = -3

Simplify the square root (Picture provided)
Elodia [21]

For this case we must find the value of the following expression:

\sqrt {8 ^ {17}}

We have to:

8 ^ {17} = 8 ^ 1 * 8 ^ {16}

Substituting:

\sqrt {8 * 8 ^ {16}}

By definition of properties of powers and roots we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So:

8 ^ {\frac {16} {2}} * \sqrt {8}\\8 ^ 8 * \sqrt {8}

So we have to:

\sqrt {8 ^ {17}} = 8 ^ 8 * \sqrt {8}

Answer:

8 ^ 8 * \sqrt {8}

Option A

PLEASE HELP ASAP!!!!!!
Dafna1 [17]

Answer:

Step-by-step explanation:

Just multiply the sides. For example, the roses take 8x4=32 feet. if we want to know the area of Zinnias, we multiply the sides 8x12 and remove the roses, which would be 8x12-32=96-32=60 for the Zinnias.

For a)

The roses take 8x4

Zinnias take 8x12 - roses

Snapdragons take 16x12 - roses - zinnias

Petunias take 16x20 - snapdragons - zinnias- roses

b) The entire area of the garden is 20x16=320 square feet

The area of the Zinnias(including roses) is 8x12 = 96 square feet

To get the percent, we divide the smaller number by the bigger number and multiply by 100 or in practice 96/320x100=30%

c) Let's see the progression here. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We have to subtract all other rectangles or the new area would be 480 - (20x16) = 160 square feet

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 105°, a
Akimi4 [234]

Answer:

The area of triangle is 110.10cm^{2}

Step-by-step explanation:

It is given that AB=19cm, BC=12cm and ∠B=105°

Now, Area of the triangle ABC=\frac{1}{2}acsinB

=\frac{1}{2}{\times}12{\times}19{\times}sin105^{\circ}

=6{\times}19{\times}(0.965)

=110.10cm^{2}

Thus, the area of triangle is 110.10cm^{2}
