Answer:
x² +7x +10
Step-by-step explanation:
The distributive property is used for this purpose.
(x +2)(x +5) = x(x +5) +2(x +5)
= x² +5x +2x +10 . . . . . use the distributive property again
= x² +7x +10 . . . . . . . . combine like terms

Answer: 6 ounces</h3>
========================================================
Work Shown:
(6 servings)/(4 oz of sauce) = (8 servings)/(x oz of sauce)
6/4 = 8/x
6*x = 4*8
6x = 32
x = 32/6
x = 5.333 approximately
x = 6 we round up despite 5.333 being closer to 5, than it is to 6.
If we went with 5 ounces, then we wouldn't clear the hurdle needed to serve 8 people.
The section below goes over why this is the case in more detail.
---------
6 servings : 4 ounces
6/4 servings : 4/4 ounces
1.5 servings : 1 ounce
So one ounce of sauce gets us 1.5 servings.
If we multiply both sides by 5, then,
1.5 servings : 1 ounce
5*1.5 servings : 5*1 ounce
7.5 servings : 5 ounces
This shows that 5 ounces of sauce will only produce 7.5 servings, which comes up short compared to 8 servings.
If we multiplied both sides by 6, then
1.5 servings : 1 ounce
6*1.5 servings : 6*1 ounce
9 servings : 6 ounces
This shows that 6 ounces of sauce yields 9 servings. We've gone overboard, but it's better to do that than come up short.
Answer:
23.590 feet
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship between trig functions and sides of a right triangle:
Tan = Opposite/Adjacent
Here, that means ...
tan(65°) = height/(11 ft)
Multiplying by 11 ft, we get ...
height = (11 ft)tan(65°) ≈ 23.5896 ft
height ≈ 23.590 ft
<span>
You find the circumference.</span>
<span /><span>It is: π x D.</span>
<span>The radius is 20m, which is half the diameter.</span>
<span>So 20 x 2 = 40m.</span>
<span>So we do 40 x Pi (3.14) </span>
<span>The answer is 125.6.</span>
<span>So you ran 125.6 meters to 1dp.</span>
