B. It’s bases are congruent
Explanation: A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.
Lets assume center point of circle as O
OD is the radius of circle . so OD is also 7
All the sides of the triangle are equal . so angle at the center O is 60 degree.
radius = 7
Length of arc CD =

Answer:
92 tablespoons
Step-by-step explanation:
16 tablespoons = 1 cup, in the recipe you need 1/4 cup for a batch, Rhonda needs 23 batches, so 23/4 to get the 1/4 cup, that's 5.75 cups, then you do 5.75*16 to get the tablespoons
Answer:
(4x + 5)(x² + 25)
Step-by-step explanation:
Given
4x³ + 5x² + 100x + 125 ( factor the first/second and third/fourth terms )
= x²(4x + 5) + 25(4x + 5) ← factor out (4x + 5) from each term
= (4x + 5)(x² + 25)
Answer:
1. y = x + 7
Step-by-step explanation:
Find the slope
Choose two points and find the slope using rise/run
(1,8) (2,9)
9-8/2-1
1/1 = 1 = m (slope)
Find b using the slope and one point
m=1 (1,8)
8 = 1 (1) + b
8 = 1 + b
7 = b
Fill in m and b into y = mx + b
y = 1x + 7
