Step-by-step explanation:
sad face
Answer:
4x + x + 7) - 2x+8 - 4 by substituting x= 1 and x = 2. А. 6x + 11 B. 3(x+7) C. 2(3x + 16) D. 3x + 16
Step-by-step explanation:
Answer:
answer: 148
Step-by-step explanation:
To find surface area you have to do all sides and multiply base x height so The top and bottom would be 11 x 2 = 22 the sides would be 4 x 2 = 8 the front and back would be 11 × 4 = 44 sense each face has a matching one each of these will be added twice so 22 + 22 + 8 + 8 + 44 + 44 = 148 So 148 is our surface area Hope this explains well!
Its an isosceles triangle because there are two sides that are the same length
The figure shows a right triangle at each corner with legs 3 and b and hypotenuse 4. The Pythagorean theorem tells you the sum of the squares of the legs is equal to the square of the hypotenuse:
3² + b² = 4² . . . . . . put the numbers into the Pythagorean formula
9 + b² = 16 . . . . . . . evaluate the squares
b² = 16 - 9 = 7 . . . . subtract 9 to isolate the variable
b = √7 . . . . . . . . . . undo the square operation by taking the square root
