Distributive property: <em>a(b + c) = ab + ac</em>.
We have 18 + 24
18 = 6 · 3
24 = 6 · 4
Therefore
18 + 24 = 6 · 3 + 6 · 4 = 6 · (3 + 4)
<h3>Answer: 18 + 24 = 6 · (3 + 4)</h3>
Answer:
a. 42, 48
Step-by-step explanation:
The angles being complementary means their total measure is 90°.
(12q -9) +(8q +14) = 90
20q +5 = 90 . . . . . . . . . . . simplify
20q = 85 . . . . . . . . . . . . . . subtract 5
q = 4.25 . . . . . . . . . . . . . . . divide by 20
Now, put this value into the expressions for the angle measures:
12q -9 = 12·4.25 -9 = 42
8q +14 = 8·4.25 +14 = 48
These two angle measures total 90, so our answer checks OK.
The measures of the angles are 42 and 48 degrees.
Yes, sqrt of 1815, cannot be rationalized
Answer:
5x = -2 + 10 + 5.
Step-by-step explanation:
3x - 5 = - 2 + 10
Add 5 to both sides:
5x - 5 + 5 = -2 + 10 +15
5x = -2 + 10 + 5 (answer).
Answer:
48
Step-by-step explanation:
3/5=x/80
cross multiply
5x=240
x=48
