The area would be (x+3) (4x-1) which is 4x^2 +11x -3. The perimeter is 2(x+3) plus 2(4x-1) which is 2x +6 plus 8x-2 which is 10x +4. If x=7 then the perimeter is 74 ft.
Answer:
12
Step-by-step explanation:
84-54=30
30/2.5=12
a dilation with a scale factor of 4, is multiplication by 4 each side, so we need the measure of the side CD and then multiply by 4 to find C'D'
we can notice tht length of CD, is 3 squares,multiplying by 4 the new length is 3x4= 1 2 squares
Step-by-step explanation:
step 1. (-0.4)(0.16) = -0.064
step 2. (0.625)(-0.08) = -0.05
step 3. -1.2(-5.1) = -6.12
