If and , find .<br><br> A. <br> B. <br> C. <br> D.
trapecia [35]
Answer: option D. 2x^2 + (3/2)x  - 5

Explanation:

1) polynomials given:

 f(x) = x/2 - 2 and g(x) = 2x^2 + x - 3

2) question: find (f + g) (x)

That means that f(x) + g(x), so you have to add up the two polynomials given.

3) x/2  - 2 + 2x^2 + x - 3

4) Combine like terms:

a) terms with x^2: you only have 2x^2, so it is not combined with other term.

b) terms with x: x/2 + x

that is a sum of fractions: x/2 + x = [x + 2x] / 2 = 3x / 2 = (3/2)x

c) constant terms: - 2 + (-3) = - 2 - 3 = - 5

5) Result: 2x^2 + (3/2)x - 5

That is the option d.

An apartment building contains 100 units.The one-bedroom units rent for $495 per month and the two bedroom units rent for $600 p
aliya0001 [1]
We have two equations

One to for the total number of units, to distinct them from 1 bedroom units or 2 bedroom units

x- one bedroom units
y- two bedroom units

x+y= 100

495x+600y= 55,275


We can try to plug in these values for y since it’s asks “how many two bedroom apartments are there” and see if it works out

495x+600(45)= 55,275

495x+27000=55275
-27000 -27000

495x= 28275
/495 /495

x=57.12

There can’t be 57.12 units so A is wrong

495x+600(55)= 55,275

495x+ 33000= 55275
-33000 -33000
495x =22275
/495 /495

x=45
This could work so B is the answer , you could go ahead and try C and B but most likely the answer is B

Find the missing length of the figure.
andrezito [222]
a^{2} + b^{2} = c^{2}

4) 16^{2} +63^{2} =4225 =  c^{2}
c= \sqrt{4225}

Missing length= 65cm

5) 13 ^{2}- 5^{2} =144
b= \sqrt{144}=12
12 ^{2}+35 ^{2}=1369
c=\sqrt{1369}

Missing length =
 37cm
