Answer:
The PERIMETER P is the distance around the rectangle.
Let's call the width of the rectangle W and the length of the rectangle L.
As you go around the edge there two equal lengths and two equal widths.
The formula for the perimeter of a rectangle is P=2*L+2*W.
P=2L%2B2W
Substitute 290 for P and 62 for the width.
290=2L%2B2%2862%29
Solve for L.
290=2L%2B2%2862%29
290=2L%2B124
290-124=2L
2L=166
L=83
The equation L=83 means that the length is 83 cm.
CHECK your work.
2(62)+2(83) = 124+166 = 290cm.
The length of the rectangle is 83cm.
Answer:
Each number is being multiplied by 3.
Thr next 3 numbers would be, 486, 1,458, and 4,374
D, it makes the most sense
9h^2+42h+49
no common factors
trial and error
try first term and last term
all sings are positive since last term and middle terms are possitive
factor leading term and coeficient and try those
9=3*3
49=7*7
(3h+7)(3h+7)
9h^2+21h+21h+49
9h^2+42h+49
true
(3h+7)(3h+7)=(3x+7)^2
answer is (3h+7)^2
answe ris ths second one
This is easy just find out what 5^2 equals which will be 5x5=25 (when dealing with a squared number you will always times it by itself. so if you had 10^2 it would be 100.) so now that we know 5^2 is 25 we then can add the 20 which gets 25+20=45! Hope this helps!
