<u><em>Answer:</em></u>
15(1+3)
<u><em>Explanation:</em></u>
<u>The distributive property can be generally expressed as follows:</u>
ab + ac = a(b+c)
<u>The given expression is:</u>
15 + 45
<u>We know that:</u>
15 = 1*15
45 = 3*15
<u>Therefore, the given expression can be written as:</u>
1*15 + 3*15
<u>Taking 15 as a common factor and applying the above rule, we will reach the following expression:</u>
15(1+3)
Hope this helps :)
Please, see the offered decision:
1) common equation for lines is y=kx+b. If k₁=k₂ (for line 1 and line 2) ⇒ 'line 1' || 'line 2'.
2) for line 3x+5y=6 k= -3/5. It means (according to item 1) for unknown line k is the same (-3/5).
3) using points (0;3) it is easy to find parameter b (x=0, y=3) via y=kx+b:
3=0*(-3/5)+b ⇔ b=3.
4) finaly (k=-3/5; b=3):
Answer:
D
Step-by-step explanation:
It's supposed to ask you to find the intersection of two lines
Answer:
This question cannot be solved.
Step-by-step explanation:
It has more than one equal sign; there is no way to compute this.
Answer:
<GBF
Step-by-step explanation:
<GBF is congruent to <CBE because they are vertical angles.
The vertical angle theorem states this is true.
Vertical angles are formed by a pair of intersecting lines and are the angles directly across from each other.
Since <GBF and <CBE are vertical angles, they are hence congruent.
