Answer:
x = 3 2/3
Step-by-step explanation:
Given
3x - 4 = 7
Add 4 to both sides of the equation
3x - 4 + 4 = 7 + 4
3x = 11
Divide both sides by 3
3x/3 = 11/3
x = 3 2/3
Answer:
96 inch²
Step-by-step explanation:
there are 2 shapes,
1. a square
2. a triangle
lets find the area of the square first,
<u>AREA = SIDE × SIDE</u>
= 8 × 8
= 64 inch²
now, area of triangle ,


so, total area is :
area of square + area of triangle
= 64 + 32
= 96 inch²
Answer:
how do we graph on here
Step-by-step explanation:
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
787.50
You multiply 250 by .05 to get 12.50, then you add it to 250 to get 262.50, and multiply it by 3 to get 787.50
