Step-by-step explanation:
Since area of Square A = 7 ft²,
Side length of Square A = √7 ft.
Length of Rectangle B = √7 ft
Width of Rectangle B = 4/√7 ft
Hence Area of Square C
= (4)² / (√7)² ft² = 16/7 ft².
Answer:
B
Step-by-step explanation:
For the three rectangles:
30x17=510
30x10=300
30x21=630
REMEMBER: the formula for solving triangles are Area = 1/2 base x height
For the 2 triangles:
1/2x21x8 = 84
And since there are 2 triangles that are both the exact same, you do 84x2, which equals 168
Finally, you add all the numbers together:
510+300+630+168 = 1,608
Which looks like is letter B on your paper
Answer:
y = -4x - 3
Step-by-step explanation:
Slope = -4
y-intercept = -3
Answer:
4x+y add like terms ... -5+9=4 and -y(or -1)+2y=y
Answer:
No
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.
31² = 961
16² + 30² = 256 + 900 = 1156
Since 961 ≠ 1156 then the sides do not form a right triangle.
