Answer:
Assume that the formula is true for the (k+1)term
Step-by-step explanation:
I learned this in class a couple weeks ago in intermediate algebra
Answer: triangle 1, triangle 2, and triangle 3
Step-by-step explanation:
Triangles 1 and 3 are congruent by SAS. So, by CPCTC, all three sides are congruent, making triangle 2 congruent to them as well by SSS.
Answer:
C. 3 in x 6 in
Step-by-step explanation:
Jammal cuts the block in a straight line parallel to one side... so the section revealed when he finishes his cut will be identical as the parallel side to which the cut is done.
We know the the left side of the prism on the image is 3 inches wide and 6 inches high... so that will also be the dimensions of the exposed cross section.
The answer is then 3 inches y 6 inches. The thickness of the block (5 inches) has no impact on the exposed area of the cross-section.
No.
The ratio of the areas is the ratio of the squares of the scale factor.
So it's 2^2 : 5^2 = 4:25
Answer:
Ok, so I hope I understood the task. Here goes nothing
Step-by-step explanation:
So, first we calculate the area of the big rectangle,
(√63+√28)*√45 = 15√35
Then we calculate the area of the small rectangle
√7*√5 = √35
Then we do this to get the area left
15√35 - √35 = 14√35
Then we take

That should explain it
