Answer:
The area is 72 cm².
Step-by-step explanation:
Since it is equivalent triangle
h = b
so,
b + b + b (since all sides are equal)= 36 cm
3b = 36 cm
or, b = 36/3
so, b = 12 cm
so
area of triangle = (1/2)×b×h
= (1/2)×12cm×12cm
= 6cm × 12cm
= 72 cm²
Answer:

Step-by-step explanation:
To solve the equation, isolate x. Whatever you do to isolate x one on side, you must do to the other.
1) Multiply both sides by 9 to get rid of the fractions.

2) Distribute the 3 to 8x and 15. Then, combine like terms.
3) Move the 66 to the other side, subtracting 18 by 66, then divide each side by 20 to finally isolate x.

Thus,
.
I say left because you have a straight line, i goes through 0,0 and every time it goes over 1 and up by 3.
Answer:
= 85
Step-by-step explanation:
given m = - 2, and n = -4
Substitute the given values into the polynomial expression:

![[(-2)^{4} + 5] - (-4)^{3}](https://tex.z-dn.net/?f=%5B%28-2%29%5E%7B4%7D%20%2B%205%5D%20-%20%28-4%29%5E%7B3%7D)
= (16 + 5) - (-64)
= 21 + 64
= 85
Therefore, the correct answer is 85.
