Answer:
1. a. 3xy²(7x²y³ + 5x - 4y)
2. a. (3x + 2)(5x + y)
3. d. (2a + b)(5x - 4)
Step-by-step explanation:
For #1, your answer was missing an exponent, which I boldfaced. Every term has a <em>y</em><em>²</em><em> </em>in common. Then, in numbers 2 and 3, just factor each group one at a time.
Ex: [10ax + 5bx] - [8ay - 4by]
The linear equation is “y = 1/4 + 40”.
Answer:
dependent
Step-by-step explanation:
The formula for a trapezoid is a=a+b/2 x h
so plug that back into the equation and you get
15=10/2 *h
15=5*h
from here, you know that 15/5 equals 3 and therefore the height of the trapezoid is 3.
Good Luck on ur Big Test!
Answer:
the missing side value is 6.7.
Step-by-step explanation:
so the Pythagorean theorem is a^2+b^2=c^2, but since we are missing the b slide the equation now is 7^2-2^2=b^2. now you may not understand why we are missing the b side. so in the Pythagorean theorem, the a and b slides dont really matter, as long as the c side is the hypotenuse, or the longest slide in a triangle. so 7squared is 49, 2 squared is 4, so 49-4= 45, but its 45squared because the equation is c^2-a^2=b^2 so now we know that 45 is b squared, we just have to square root 45, to get about 6.7.
