Answer:
5(x+3)
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
GCF = 55
2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
5(\frac{5x}{5}+\frac{15}{5})5(
5
5x
+
5
15
)
3 Simplify each term in parentheses.
5(x+3)5(x+3)
If x = -b/2a, then 2a = -b / x so a = -b / 2x or a = b / -2x
So the denominator is -2x because it has to take the minus sign that the numerator refused to take ;-)

Answer:
49.3 feet
Step-by-step explanation:
Shadow lengths and object heights are considered to be proportional, so we have ...
tree height/(tree shadow) = Andrew's height/(Andrew's shadow)
height / (85 ft) = (5.8 ft)/(10 ft)
height = (85 ft)(5.8/10) = 49.3 ft
The tree is 49.3 feet tall.
Answer:
An angle showing a turn through 1/8 of a circle is smaller
Step-by-step explanation:
we know that
A complete circle represent 360°
so
<em>An angle showing a turn through 1/8 of a circle is</em>
<em>An angle showing a turn through 1/3 of a circle is</em>
therefore
An angle showing a turn through 1/8 of a circle is smaller
Answer:
y = 105 ÷ 6 = 35/2
Step-by-step explanation:
∵ 15/3 = 2y/7
∴ 2y × 3 = 15 × 7
∴ 6y = 105
∴ y = 105 ÷ 6 = 35/2
