Answer
(10x+15) + (5x)=180
X=11
Answer:
5(x+4) ≥ 19
x ≤ -1/5
Step-by-step explanation:
5(x+4) ≥ 19
5x + 20 ≥ 19
5x ≤ -1
x ≤ -1/5
Answer:
1. B. BD
2. C. 15
3. A. 2
Step-by-step explanation:
1. From the figure,
∠DAB = ∠DAC
Therefore, BD is the bisector of ∠ABC.
2. From the figure, IG = GH
3x = 5x - 10
10 = 5x - 3x
2x = 10
x = 5
So, GH = 5x - 10
= 5(5) - 10
= 25 - 10
= 15
Therefore, GH = 15.
3. From the figure,
∠DAB = ∠DAC
10y = 8y + 4
10y - 8y = 4
2y = 4
y = 2
Answer:
1: 152
2: 152
3: 152
4: 28
Step-by-step explanation:
1-3: They are all congruent. So if you look at the given angle, it is the same as 1-3.
4: This one is tricky. Since a straight line is 180, you have to subtract 180-152.
Hope this helps!
For the given trinomial

We need to multiply a by c

We split the middle term with these two factors

To obtain,

We now factor

This implies
