Answer:

31.5 units^2

Step-by-step explanation:

Rectangle area (RA) = l × w

Triangle area (TA) = (bh)/2

RA = 3 × 7

RA = 21

TA = (7 × 3)/2

TA = 21/2

TA = 10.5

(Triangles are congruent as shown by the lines on each side of the triangle so I can calculate area of both of them together as I just did)

Add areas together

21 + 10.5 = 31.5

What is the y-intercept of the line y + 11 = -2(x +1.5)? - y-intercept = | = I

aleksandrvk [35]

Answer:

The y intercept of the line is (0, -14).

Step-by-step explanation:

we are given the equation

y + 11 = -2(x + 1.5)

The y-intercept of the line is the point where x = 0,

Substituting x = 0 into the expression:

y + 11 = -2(0 + 1.5)

y + 11 = -0 – 3

y + 11 = -3

y = 11 – 11 = -3 – 11

y = -14

Thus, The y intercept of the line is (0, -14).
