Answer:
I would say 8.
Step-by-step explanation:
Using the Pythagorean Theorem, a2+b2=c2.
7^2+5^2=c^2
49+25=74
Now find the square roots of all numbers...
7+5= about 8.
Answer:
showing bellow
Step-by-step explanation:
Let me use an exsample to show this.
Nash is making a framed enlargement of a Mary Cassatt postage stamp to present to a retired postmaster. He enlarges the stamp using a scale of 2 inches to 1 centimeter. If the actual length of the stamp is 3 centimeters and its width is 5 centimeters, what are the dimensions of the scale picture?
6 inches by 10 inches
Step-by-step explanation:
It tells us that the scale is 2 In: 1 cm so we know that for every centimeter long or wide the stamp is the enlardged scale is two inches.
2 times 3 is 6. 6 inches. we are multiplying two inches by the number of centimeter long it is.
5 times 2 is 10 inches. we are multiplying two inches by the number of centimeter wide it is.
therefore the enlarged stamp is 6 In by 10 In.
Hope this helps :)
Step-by-step explanation:
4x2=−9x−4
Step 1: Subtract -9x-4 from both sides.
4x2−(−9x−4)=−9x−4−(−9x−4)
4x2+9x+4=0
For this equation: a=4, b=9, c=4
4x2+9x+4=0
Step 2: Use quadratic formula with a=4, b=9, c=4.
x=
−b±√b2−4ac

Answer:
z+11y/5 = x
Step-by-step explanation:
Since you are solving for x, you want to isolate the variable. You do that by adding 11y to both sides, which cancels out the -11y. From that you should have z+11y = 5x. To cancel out the 5x you need to divide both sides by 5 to get z+11y/5 = x. Hope this helps :)
