Answer:
-3.5
Step-by-step explanation:
We have to find the distance between x and z along the y-axis.
This will be: 5 - -6 = 11 units
1/5 th of 11 = 1/5 × 11
= 11/5
= 2 1/5 = 2.5
Now add 2.5 to -6
2.5 + -6 = -3.5
The value of y = -3.5
Step (1) is incorrect. To divide by a number means to multiply by the reciprocal. In step (1) they did not convert the polynomial into its reciprocal.
Answer:
b= 26
Step-by-step explanation:
there are 2 triangles
area of the right angles triangle
1/2bh= 1/2 x3 x4 = 6cm²
for the next triangle we use pythagoras theorem to calculate the height
3²+4² = h² = 9+16 = 25
h = √25 =5
1/2bh = 1/2 x 5 x8 = 20
adding the two areas will give the area of the figure = 20 + 6 = 26
