Area = b*h and in some cases * 2 so you need to do this, 64*52 + 40*28= 4448 yd2
You didn't write the (-2/7) as a power; you were supposed to do b to the power of -2 over 7, which is what the other person done in your other post regarding this
Answer:
x² + 6ax + 4bx + 5a² - 5b²
Step-by-step explanation:
(x+5a+5b )(x+a-b)
x² +a x -bx +5ax + 5a² -5ab + 5bx + 5ab -5b²
x² + 6ax + 4bx + 5a² - 5b²
X^9/32...... in other words.... x to the nine over thirty second power
