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 answer to this question is 39.28; 65.12
Answer: width is 12, length is 16
Step-by-step explanation:
A= l*w
l=w+4
A=w(w+4)
factor
(w+16)(w-12)
w= -16 or w=12
width is 12, length is 16
Answer:
33) $8440
34) $67,964.62
Step-by-step explanation:
33) The interest on 1 for 270 days is ...
... I = Prt = 1×0.09×(270/360) = 0.0675
so the proceeds from a loan with a face value of 1 will be
... 1 - 0.0675 = 0.9325
We want to find the face value of a loan with proceeds of $7870.30, so we need to solve the equation ...
... $7870.30 = P×0.9325
... P = $7870.30/0.9325 = $8440
34) The discount is computed from ...
... I = Prt = 70,000×0.063×(24/52) ≈ 2035.38
Then the amount Smith will pay for the T-bill is ...
... $70,000 -2035.38 = $67,964.62
Answer:
assume z is equal to 5.
log(z^4/5) equals log(5^4/5) equals log(5^3) equals 2.096910013.
4 * log(5) - log(5) equals 2.096910013.
they give you the same answer.
this means they're equivalent.
