121 x 12 = 1452 so over 1500 is not a correct estimate. Less than 1500 is the right estimate
Group and factor
undistribute then undistribute again
remember
ab+ac=a(b+c)
this is important
6d^4+4d^3-6d^2-4d
undistribute 2d
2d(3d^3+2d^2-3d-2)
group insides
2d[(3d^3+2d^2)+(-3d-2)]
undistribute
2d[(d^2)(3d+2)+(-1)(3d+2)]
undistribute the (3d+2) part
(2d)(d^2-1)(3d+2)
factor that difference of 2 perfect squares
(2d)(d-1)(d+1)(3d+2)
77.
group
(45z^3+20z^2)+(9z+4)
factor
(5z^2)(9z+4)+(1)(9z+4)
undistribuet (9z+4)
(5z^2+1)(9z+4)
We can convert 24/16 to a mixed number. It will be equivalent to 24/16.
24/16
24 ÷ 16 = 1.5
16 can go in to 24 once.
24 - 16 = 8
1 = whole number
8 = numerator
16 = denominator
Lets write our mixed number:-

This can be simplified ^^^^

So, our old mixed number simplified is

So, 24/16 is equivalent to 1.

, 2.

Hope I helped ya!!! xD
I dont lhow the answer tomorrow in the morning I will tell you
Answer:
40 ft²
Step-by-step explanation:
Divide the figure into 2 rectangles and find their areas.
The area of the smaller rectangle
= 3 × 4
= 12 ft²
The area of the larger rectangle
= (8-4) × 7
= 28 ft²
The area of the figure
= 12 + 28
= <u>40 ft²</u>
