Answer:

1,620 square inches

Step-by-step explanation:

The area of one triangle can be computed using the formula ...

A = 1/2bh . . . . where b represents the base length, h represents height

A = 1/2(18 in)(36 in) = 324 in²

Then the area of 5 flags will be 5 times that much:

fabric needed = 5 × (324 in²) = 1,620 in²

Brian will need 1,620 square inches of fabric for his 5 triangular flags.

Plz answer both for 10 points.!!! Thx for the help.

ratelena [41]

Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h

23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified

24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values

.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.

4(x−0.8)=3.8x−5.8 PLZZZ ANSWER FAST!

Hunter-Best [27]

To find the answer:
$4(x - 0.8) = 3.8x - 5.8 \\ 4x - 3.2 = 3.8x - 5.8 \\ 4x - 3.8x = - 5.8 + 3.2 \\ 0.2x = - 2.6 \\ x = - \frac{ 2.6}{0.2} \\ x = - 13$

Therefore, x=-13.

Hope it helps!
