Answer is 4.
Right angle= 90
50+ 10(4)= 90
Strictly speaking, x^2 + 2x + 4 doesn't have solutions; if you want solutions, you must equate <span>x^2 + 2x + 4 to zero:
</span>x^2 + 2x + 4= 0. "Completing the square" seems to be the easiest way to go here:
rewrite x^2 + 2x + 4 as x^2 + 2x + 1^2 - 1^2 = -4, or
(x+1)^2 = -3
or x+1 =i*(plus or minus sqrt(3))
or x = -1 plus or minus i*sqrt(3)
This problem, like any other quadratic equation, has two roots. Note that the fourth possible answer constitutes one part of the two part solution found above.
Answer: Kate = £102
Sanjeev = £153
Step-by-step explanation:
From the question, we are informed that for every £2 that kat collects, sanjeev collects £3. This csn be represented in a fraction as:
Kat = 2/5
Sanjeev = 3/5
The amount that each collects will be:
Kat = 2/5 × £255
= 2 × £51
= £102
Sanjeev = 3/5 × £255
= 3 × £51
= £153
Answer: 12
Step-by-step explanation:
I think it’s 12, don’t you do 96/8?
Answer:
c= ab + d/ a
Step-by-step explanation:
Let's solve for c.
a(c-b)=d
Step 1: Add ab to both sides.
-ab + ac + ab = d+ ab
ac = ab + d
Step 2: Divide both sides by a.
ac / a = ab + d / a
c = ab + d/ a
Answer:
c= ab + d/ a
