Answer:
=91 cm squared
Step-by-step explanation:
LET THE WIDTH BE X
the length is therefore x+6
2(x)+2(x+6)=40
2x+2x+12=40
4x=28
x=7
area=7×7+6=91
Answer:
There is no solution (since none has side length of 4 units)
Step-by-step explanation:
If V (-1,1) is one of vertex of a square, then the next vertex to V distance must be the known value of 4
VA: V to (-3,3) = √(-1 - -3)² + (1 - 3)² = √8 = 2.8
VB: to (-5,-3) = √(-1 - -5)² + (1 - -3)² = √32 = 5.7
VC: o (3,3) = √(-1 -3)² + (1 - 3)² = √20 = 4.47
VD: to (-5,3) = √(-1 - -5)² + (1 - 3)² = √20 = 4.47
VE: to (4,5) = √(-1 - 4)² + (1 - 5)² = √41 = 6.4
Answer:
2x⁴ - x² - 15
Step-by-step explanation:
(X² - 3)(2x² + 5)
[x²(2x² + 5)] - [3(2x² + 5)]
= 2x⁴ - x² - 15
Answer:
The temperature increases by a total of 12 degrees.
Step-by-step explanation:
A good way to solve a problem with positive and negative integers is to plot them on a number line and find the difference from one point to the next. On a number line, positive numbers go to the right of zero and negative numbers go to the left of zero. If we start at a temperature of -4 and count to the right on the number line until we get to +8, there will be a difference of 12. The other way to set up the problem is to subtract the numbers, 8-(-4)=12.
