Answer:
Option A (7×3) + 1/2(7×6)
Step-by-step explanation:
Divide this shape into a square and a triangle
For area of square the formula is
Area = A = L ×W
From shape of square
7 seven boxes are yellow so L=7 and width W=3
A = 7 × 3
For triangle formula is
A = (1/2)bh
A = (1/2)(7×6)
Add them
A = (7×3) + 1/2(7×6)
Answer:
The black triangle
Step-by-step explanation:
We can start by noticing that the pattern is repeating every five shapes.
So we know that The shape given every number divisible by 5 is going to be the white circle.
So the 5th shape, 10th shape, and 105th shape are examples of times there will be a white circle.
We can now see that 214 is almost divisible by 5, but -1. Let's imagine the number is 215 for a second. Then the position would be the white circle. Now what's right before the white circle? The black triangle.
The black triangle is in the position.
Answer: A
16x^2 - 56xy + 49y^2
4^2x^2 - 2 • 4x • 7y + 7^2y^2
(4x)^2 - 2 • 4x • 7y + (7y)^2
=(4x-7y)^2
