Answer:
47x - 9
Step-by-step explanation:
-4(4x + 4) + 7(1 + 9x)
-16x -16 + 7 + 63x
47x -9
You can find what x = because there is no = sign. This is in simplest form.
Answer:

Answer:
the answer is 5
Step-by-step explanation:
Area = 1/2 x base x height
Base = area x 2 / height
Base = 6 1/4 x 2 = 12 1/2 / 3 1/3
Base = 3 3/4 m
Answer:
A=9in,b =9in
Step-by-step explanation:
This is a right angled triangle
Formula = a2×b2=c2 (ie sq of both adj sides equals the sq of the longest side)
So, a2 × b2 = c2
But both sides are equal, so we can as well say 2(a2) = (9|2)^2
2a^2 = 162
Divide through by 2
A^2 = 81
So, a = |81
A = 9
And since both sides are equal, a = b = 9
