X2 + 4x - 21
Answer: (x + 7)(x - 3)
To convert a mixed fraction into a first you need to convert it into an improper fraction.
To do that multiple 87 to 25 and then add 24
If you do that you will get 2199/25
then divide the numerator by the denominator.
87.96 is what you will get if you divdie it correctly
The parts of a circle are the r<em>adius, diameter, circumference, arc, chord, secant, tangent, sector and segment.</em>
Radius:
The distance from the center to any point on the circle.
Diameter:
The distance across the circle through the center point.
Circumference:
The distance around a circle.
Arc:
arcs in the same circle that have exactly one point in common. measure of arc divided by 360 multiplied by the circumference. the length of an arc. semicircle. an arc that is half of a circle; always measures 180 degrees.
Chord:
a line segment that connects two points of a circle.
Secant:
A secant is a line that intersects a circle in two points.
Tangent:
A tangent is a line that intersects the circle in exactly one point.
Sector:
region bounded by an arc of a circle and the two radii to the arc's endpoints. - A sector is like a "pizza slice" of the circle. It consists of a region bounded by two radii and an arc lying between the radii.
Segment:
A segment or length of a segment with one endpoint at the center of the circle.
Answer:
b) 6/7
c) 14
Step-by-step explanation:
b) Scale Factor = Red/(Red+Blue) = 8/(8+6) = 8/14 = 6/7.
c) x = 8+6 = 14.
EXTRA TIP: If you aren't sure, think about wheter these triangles are isosceles(from the diagram). Hope this helps!
B,C,A is the answer to your question
