Answer:
x²+5x-10=0
x²+(2-7)x-10=0
x²+2x-7x-10=0
x(x+2)-7(x+2)=0
=x+2=0
=x=-2
=x-7=0
=x=7
hope may be right.....
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
Here is a definition
Integers. The integers are ..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. ... For example, -5 is an integer but not a whole number or a natural number.
Answer:
AB = 74°
Step-by-step explanation:
Minor arc AB is equal to the measure of the central angle APB , then
∠ APB = 360° - 286° = 74° , thus
minor arc AB = 74°
Answer/Step-by-step explanation:
1. The vertex of am angle is formed when two lines join together. The vertex of the angle shown in the diagram is located outside the circle.(<R)
2. The lines that created <FRT (lines FR & TR) are secants
3. The major arc = FT = 140°
minor arc = QS = 44°
4. Formula of Exterior angles of a circle = (major arc - minor arc)/2
x = (140 - 44)/2
x = 96/2
x = 48°
Answer:
1) 8 m^3
2) 125 + 25
3) 8
Step-by-step explanation:
1) It's a cube shape => length = width = height = 2 m
Volume = length × width × height = 2 × 2 × 2 = 8 m^3
2) 5^2 + 5^3 = 150
25 + 125 = 150
3) Now she is 8 years old (8 = 2^3)
Next year she'll be 9 years old (9 = 3^2)
