Find the area of the figure.

Otrada [13]

Answer:

20 square units

Step-by-step explanation:

The figure shows a triangle whose;

Base AC is 8 units
Height is 5 units

We are supposed to get its area;

Area of a triangle is given by the formula;

Area = 0.5×b×h

Thus;

Area = 0.5 × 8 units × 5 units

= 20 square units

Hence, the area of the figure is 20 square units

Expand and simplfy (2x+1)(x+3)

Nina [5.8K]

Answer:

(2x+1)(x+3)

2x(x+3)+1(x+3)

2x2+6x+x+3

2x2+7x+3 (2x2 means two x square)

if you want you can also multiply 2x+3 by x+3

like this:

(2x+1)(x+3)

x(2x+1)+3(2x+1)

2x2+x+6x+3

2x2+7x+3 (2x2 means two x square)

They will both give you the same answer.

The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi

PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

$a^2+b^2=c^2$

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

$10^2+b^2=26^2$

Solve the exponents

$100+b^2=676$

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

$100-100+b^2=676-100$

$b^2=576$

Take the square root of both sides

$\sqrt{b^2}=\sqrt{576}$

b=24

So, the other leg is 24 mm
